Notes on the startup of the oldest programmers: full-text search, data mining, and recommendation engine application 50

Micro-Innovation
Wu Yan decided to give the first batch of advertising customers to Wang Wenbin, and then he came directly to Wang Wenbin.
Wu Yan knocked on the door gently at Wang Wenbin's office door.
"Please come in !" Said Wang Wenbin.
Wu Yan opened the door of Wang Wenbin's office. Wang Wenbin glanced at the computer screen and looked up. Wu Yan said, "Is there something for me ?"
"Oh, it's something ." As Wu said, he sat in the chair in front of the table of Wang Wenbin and then said, "Well, I contacted a group of advertisers some time ago, and I have basically decided on it, I want you to final the details and sign the contract!"
I thought Wang Wenbin would be very happy to hear the news. I didn't expect Wang Wenbin to have no happy expression after hearing the news, but a face of confusion. Wang Wenbin secretly thought that Wu Yan would not give himself the customers he had already obtained. Maybe Wu Yan was just making his own decisions, and then pushed it to himself, if you cannot sign it, it can be said that you are incompetent. It is really sinister.
Thinking of this, Wang Wenbin said, "Is it true? That's great, but recently I am quite nervous about developing a franchisee. I think you should sign it yourself. You followed the previous paragraph, which is more efficient ."
Wang Wenbin wants to let it go, which is a little unexpected.
Wu Yan went on to say: "In fact, this group of customers were introduced by my classmates. Now we have all talked about them. I think you are responsible for the sales work, so it is more appropriate for you to do it, if you have any questions, please come to me and I will coordinate this matter!"
"Oh, okay !" Wang Wenbin was a little helpless. Even if this is true, Wang Wenbin is not happy. He does not want to see Wu Yan make achievements, because in that case, he may have no time to come.
"I will send you their contact information in a moment. You can contact them. It should be okay !" As Wu said, he got up and quit.
Then Wu Yan sent the contact information of these people to Wang Wenbin, so he waited for the good news.
It seems that Wang Wenbin is really competent. In less than a week, he completed all these customers and signed nearly 1 million of the advertising contracts. Although he is only accounts receivable in the financial statement, however, this has produced a solid business revenue, which can be regarded as a huge progress. We should celebrate it.
With this idea, Wu Yan found Liang xiujuan and talked about it.
After listening to Wu Yan's thoughts, Liang xiujuan said, "Yes, we should celebrate. How can we celebrate ?"
Wu Yan thought for a moment and said, "I think we can let everyone go to Jiuhua villa for a good meal and then get a hot spring ."
Liang xiujuan listened to Wu Yan's suggestion and said, "The idea is good, but the cost is not small, or ......"
"Well, I personally pay the bills this time. I understand that although the company has some sales revenue, it hasn't been recorded yet, and the finance is still very tight !" Wu Yan said.
"Are you going to pay? Your salary is not high now, OK ?" Liang xiujuan asked with no confidence.
"No problem. I don't have to spend more than dinner and take a taxi every month. I haven't paid any more than half a year. It should be enough for 20 thousand yuan !" Wu Yan said with confidence.
"Well, let's arrange for the Administrative Department. Let's hire a car and choose to have a workshop there at noon on Friday. Then we'll have a hot spring and come back in the evening. What do you think ?" Liang xiujuan asked.
"Okay, OK! Please arrange it !" Said Wu.
At noon on Friday, the company hired a car and pulled everyone directly to Jiuhua villa to start a Celebration Banquet.
This celebration banquet was hosted by Liang xiujuan. She was very good at this aspect.
After all the dishes were completed, Liang xiujuan first said: "Everybody, today we are here for dinner, mainly to celebrate that the company has recently signed a batch of large orders, achieving zero business breakthroughs, everything is difficult at the beginning, and our future development will surely become more and more smooth!"
Everyone raised their hands when they heard the good news.
Liang xiujuan went on to say, "We have to thank Mr. Wu for coming to dinner here today. This celebration was done by Mr. Wu with his personal savings. Let's thank Mr. Wu, may I ask Mr. Wu to say a few words."
There was another round of applause from the employees.
Wu Yan followed Liang xiujuan's words and said, "I think this is the case. First of all, I think everyone has worked very hard some time ago and has finally achieved today's achievements. We should definitely celebrate it. Second, our company is still in a difficult period, so we still need to work hard. I would like to thank you for your support in the previous section ."
Wu Yan paused and said, "In fact, the greatest credit for this achievement should be recorded in Mr. Wang, who signed these customers, come on, let's have a cup of King!"
Wu Yan's words surprised Wang Wenbin, who had been sitting on the side, and said, "Where, where! It is the result of everyone's efforts !"
While talking, Wang Wenbin met his colleagues and swallowed up the beer.
Put down the wine glass, Wu Yan said: "Everyone is at will. Today's main task is to have a good time !"
Liang xiujuan touched Wu Yan and whispered to Wu Yan: "didn't you say that you found these customers ?"
"Yes, why ?" Wu Yan asked.
Liang xiujuan then asked, "Did you give these customers to Wang Wenbin ?"
"Yes, I think he is in charge of sales. He is more suitable !" Wu Yan replied.
"Have you noticed that the development of the franchisee has been slow since he is in charge of sales ?" Liang xiujuan asked.
"Yes, I have also noticed that he has just retired some time ago and has not been adjusted psychologically. I will give the customer to him this time to let him figure it out, do your best in the future!" Wu Yan said.
"Ah, your thoughts are too idealistic ." Liang xiujuan said this, and then he never said anything again.
After dinner, Wu Yan found Zhang shaozhi and they joined the hot spring together. During this time, he had been doing other things, and the R & D work had not been asked for a long time, he hopes to take this opportunity to have a good chat with Zhang shaozhi.
"How are you doing recently ?" Wu Yan took the initiative to ask Zhang shaozhi.
"The functions proposed in the product function design document recently released by Zhao Qigang have basically been completed ." Said Zhang shaozhi.
"Do you think there is anything else to do for R & D in the next time ?" Wu Yan asked.
"When we discussed how to improve system concurrency some time ago, we first adopted NewSql, And then we wanted to adopt the Hadoop architecture. I think we can start to do this next step ." Said Zhang shaozhi.
Zhang shaozhi is interested in new technologies and is always looking for opportunities to use new technologies.
"Well, porting to Hadoop is not a simple task !" Wu Yan said with deep feelings.
"I am now reading the Hadoop in Action book. Basically, I have mastered the Hadoop development method completely, and I have also done some experiments on some features. I feel it should be okay to transplant it !" Zhang shaozhi said with confidence.
Wu Yan is not skeptical about this. Zhang shaozhi is still very good at technology.
"Well, well, you can make a detailed transplant plan first. Let's discuss it again ." Wu Yan said.
"Okay !" Zhang shaozhi was very excited when he agreed to his ideas.
"By the way, do you think there are any improvements to the product's functionality ?" Wu Yan asked.
"This ...... "Zhang shaozhi thought for a moment and said:" In terms of query, there are only keyword queries, and many rich query semantics cannot be displayed, but Google and Baidu both have this problem."
"Yes, there are very few advanced queries for Google and Baidu, and users are used to simple keyword queries ." Wu Yan said with deep feelings.
"Yes, it's too difficult to get an education market !" Said Zhang shaozhi.
Zhang shaozhi is not only engaged in technical research, but also has some feelings about the market. He is a graduate from a prestigious university, although he has only graduated for two years.
"Yes !" Wu Yan suddenly thought of something and said excitedly: "Lucene query syntax is rich. I think we can bring up a window next to it when users enter it in the query box, prompt the user for various query syntaxes!"
"Well," Zhang shaozhi is somewhat confused. He has no experience in Lucene.
"Well, for example, if you enter java, you can check the title, tag, and body of the article that contains java. If you enter java unit, search for articles containing java and unit in the title, tag, and body of the Article. However, if you enter + java and-unit, search for articles that contain java and contain no unit in the title, tag, and body of the article. In addition, if you enter the content caused by double quotation marks, search for articles containing all the content in double quotation marks in the title, tag, and body of the article. You can also search for the content in the title, tag, and body, which are supported by Lucene, however, because it is too complex for users to remember, it is not widely used. My idea is to use these scenarios with a floating window to prompt users, so that users can construct complex query conditions based on these scenarios when they need precise search, in this way, the search accuracy will be greatly improved." Wu Yan spoke endlessly.
After hearing this, Dr. Zhang nodded and said, "This is indeed a solution. When we have finished our work, we can consider adding this function !"
Zhang shaozhi is not as interested in technical issues such as porting this suggestion to Hadoop. He is still looking at the problem from the perspective of technical personnel. In fact, what Wu Yan said just now, it may be more helpful for improving user experience.
"It doesn't matter. If you have a hand on your side, I can do it myself. It's not a big workload !" Wu Yan said.
Wu Yan is used throughout the week to implement this query syntax Prompt window. The first step is to place the window. Because the content to be dynamically completed must be displayed under the query box, therefore, Wu Yan decided to display it on the right side of the query box. In terms of color selection, Wu Yan finally chose a pale yellow color, which is more eye-catching. In terms of representing the logical relationship, Wu Yan chose the plus or minus sign, rather than And Or, because the Chinese people are more likely to understand addition And subtraction.
In this way, after you place the cursor in the query box, the query syntax prompt box appears, and there is an option at the bottom. You can disable this syntax prompt box to pop up later, when the user enters the query condition, the query syntax prompt box will automatically disappear, so that the user can be prompted for complex query syntax without affecting other operations.
After all these functions are completed, Wu Yan selects several application scenarios and uses the query syntax or keywords only for queries. It is found that the accuracy of the query results can be greatly improved when the query syntax is used, by simply entering a few addition and subtraction numbers, you can skip several pages to select the query results, which can greatly improve the user experience.
Wu Yan directly launched the new feature and made a new task in the system. He asked users to try the new feature and share their own experience. All the work was done, let's look at the trial results for next week.
Wu Yan waited for gehua cable's hd TV installation at home on Monday morning, so he didn't arrive at the company until around noon. When he arrived at the company, he found Sun Zhengdong's email to the company, ask who launched the task without the consent of the Operation Department.
It is. Wu Yan is still used to his work style. He can do whatever he thinks, but now a company is operating and everyone has their own division of labor, therefore, we should at least inform Sun Zhengdong of things we haven't done before going online. It is really not good to go online without permission.
At this point, Wu quickly sent an email to Sun Zhengdong, explained the cause, and apologized to him. He ensured that he would follow the process and sent the email to the company. Sun Zhengdong quickly replied to the email, meaning that he just wanted to confirm that the activity was launched. Why didn't he know it? Now that he knows it, it's okay.
Finally, this thing has passed, but it is worth noting what to do in the future.
The launch of this function seems to be very popular with users. In just one or two days, hundreds of people commented on it and said that this function is really good, the original query usually involves several pages, which can be found on the first page, which is much more convenient.
Looking at these comments one by one, Wu Yan has a sense of accomplishment. He thinks that this is the true micro-innovation. He just made some changes on the interface, but it can greatly improve the user experience.
After resolving the user query problem, Wu Yan began to pay attention to the progress of the franchisee's home. In the recent period, although Wang Wenbin and Qian an Jiang have significantly reduced the number of customers going out to run, and in the recent month, they have only developed less than 10 franchisee families, obviously, they are not as keen as they were to do this before. How can they get them out of the past and work with enthusiasm? This is a problem Wu Yan has been thinking about.
