When we use search engines to search for data, the key to choosing keywords is beyond doubt. Correctly analyzing and dealing with key words is an inevitable prerequisite to improve the satisfaction of search results. At the same time, there will be new problems in the search practice, resulting in new keyword selection principles and more experience skills. Learn the key words analysis and processing of common knowledge, also will deepen our understanding of search engines.

1, master the choice of key words principle

The quality of search results is very close to the choice of keywords. From the following points to consider the selection of appropriate keywords.

(1) accurate. Accurate keyword presentation is an essential prerequisite for good search results. Improve the accuracy of the key words, need to pay attention to two aspects: first, to avoid typos, the second is to avoid ambiguous words and words. For simple, popular, easy to create ambiguity in the keyword, should be taken to add some restrictive modifiers, the search purposes to describe a complete point. For example, "Apple" rewritten as "fruit apple", search results will become more satisfied. In addition, the use of search syntax combination of keywords, can also effectively improve the search quality, such as "Dietary nutrition Science", the use of double quotes in English to make long keywords as an integral, can improve the accuracy of search results. Most of the search syntax is simple, and using a search engine takes a little time to understand its grammatical rules, which helps you find the information you need quickly and efficiently.

(2) Strive for brevity. The current search engine's ability to deal with natural language is not very strong. Therefore, when submitting a search request, it is best for the user to refine his or her ideas into a simple query that is associated with the subject of the information content that they want to find. For example, the previous example "Students of the first-grade patriotic famous sayings," If the deletion does not affect the search results of the "junior students", discard redundant "about", remove the meaning of repeated "celebrity", refined into a concise "patriotic quotes." In this way, from the search intention, select and refine the subject information of the search word, form a clear and accurate concept, can avoid the retrieval of the word lengthy and cause the search failure.

(3) representative. The key words to be able to become a typical sign of things to be queried, time, people, places can generally become a keyword to increase the representativeness of the effective limiting factors. For example, to find the title of foreign language test, if the key words as "the title of foreign language test outline", Baidu search engine retrieval results are 120,000 pieces of information. If add a time limit word "2007", plus a geographical limit word "China", plus a feature of the term "professional and technical personnel", and finally the keyword into the "2007 Chinese Professional and technical personnel title Foreign language test outline", Baidu search results are only 4 940. Therefore, the most representative and indicative keywords are essential to improve search efficiency.

2. Learn some skills of keyword selection

(1) High frequency lexical. A successful search often consists of several searches. Generally first use simple keywords for exploratory search, and then analysis, to see what is their own needs of information, pick out the high-frequency words, these high-frequency words with the original keyword design a better keyword expression search again, you can search for more satisfactory results.

(2) skillfully use "related search". The so-called related search refers to and your search key words, synonymous or similar to a series of query words. For example, in the search box to enter the "nutritional Science of Nutrition", in the Baidu page below will show the following related search: "Nutritional diet", "dietary Nutrition and Health", "diet and nutrition", "dietary Nutrition and Health papers", "diet and nutrition Lesson Plans", "Children's nutrition Diet", "Child Nutrition Diet", " Diet nutrition collocation, "Pregnant woman nutrition Diet", "more related search". These related query words are generally more commonly used, and are more likely to produce related results, sorted by search popularity below the search results page. If you are not satisfied with the search results by typing a keyword that is not appropriate, refer to "related search" to get some inspiration, or click on a "related search" item to get its results page.

(3) The flexible application of the search grammar. The search syntax is fairly easy to learn compared to other computer languages. The flexible use of the search syntax in the keywords will greatly improve our search efficiency and search accuracy. For example, I would like to download the "Nineth set of broadcasting" files on the website of Jimei University, and add "site: Site domain name" after the query content, so that the search scope is limited to the specific Jimei university site. So, in the search box input: "The nineth set of broadcasting site:jmu.edu.cn", so that the very fast speed and very accurate to find the relevant information.

(4) Select keywords according to the characteristics of the Web page. Many types of Web pages have a similar feature. For example, a novel Web page usually has a catalog page with a "Table of contents" of two characters on the page, when querying a novel, you can add the word "Table of contents" to the query keyword, as well as the software download page, usually there is a download link to the body of the Web page, and the word "download" will appear, if you want to download a software, add in the keyword " Download to improve the accuracy of your search results.

In short, the use of search engines, the choice of keywords is an accumulation of experience, through continuous practice, learn and habits to use a number of keywords, to develop a good and effective search habits, and pay attention to observation, summary, perfect, will make the search become accurate and efficient.
