How to use search engines

Recently, my "teacher +boss" has taught some techniques of using search engines. Decide to write down, let yourself comb the idea, memory clearer!

The appearance of the problem

When I need to write 404 pages in a Web application, I search for:
Java 404 redirect
Baidu gives me the answer is similar to some, the site is a problem, directly jump 404 page, Why?

The first of the answers that Google gives is:

Custom 404 Error interface.

How to search

Keywords: search for the key words
In fact, when I need to search, I do not know what I specifically to search for, I only know I have to write a 404 page. A Java 404 redirect is then entered. In fact, my keywords are not very well extracted.

In the system, there would have been a default 404 page, but the comparison of ugly, and to the user saw, the user experience will be very bad.
Write yourself a 404 page, that is, customize a 404 page, the keywords are actually:
Custom 404 Java
This time Baidu gives the answer is much better.

Look again, Google gives the answer:

So, it's critical to find the key to your problem .
(The key of finding the answer is the find the key! Suddenly want to say that this sentence English ^_^)

The choice of search engine

Keywords: using the search engine
It's easy to make judgments when you see search results. (I was shocked by what I had searched for.)
Google in the search for IT problems, the quality of the answer is really much higher than Baidu.

However, not because of this, you do not have to Baidu.
For example, when searching for a very vague thing, such as you want to improve the performance of the server, but you do not know where to start, want to search for a bit.
This time, you can do fuzzy search on Baidu, server performance, of course, there will be a bunch of ads.

Then, according to the results of the search, change the search keywords, such as: Server performance bottlenecks, server performance indicators.
At this time, Baidu will tell you a lot of information:

This time, you can learn what the bottleneck of server performance is.
Then one by one query.

也就是说，在我们对搜索的关键词了解的时候，直接上google进行搜索就好了。如果关键词比较模糊，可以先进行百度，根据查询的结果调整自己关键词，一直调整到能够表达自己意思的关键词为止。http://stackoverflow.com 这个网站不错，基本上遇到的问题在上面都可以找到答案。很强大的一个网站。

In the search, the most important thing is to know what they are searching for, that is, the keyword, and then with a forced search engine, most of the problems will be solved!

Official documents

Keywords: patience to see official documents
The official document is really a good thing, but a lot of times, just want to put their own problems directly Baidu/google out, do not have to read the document. But it often takes more time to search.
From the cost of time to see, or to see the document is more cost-effective. And is the official "authority" of Ha!
