Advanced usage of search engine

Frequent Internet users are probably not unfamiliar with the search engine, but when it comes to using you to achieve the use of ease or to be adept at it? Everything is fastidious about a skill, search engine is no exception. If you want to fully understand the use of search engine skills, may not read the following article carefully, I believe you will be able to benefit after reading.
First, advanced web search
Learning advanced Web Search will greatly improve your chances of finding information. However, most search engines will limit your search to some extent.
Second, the sensitivity of the upper case
If you are searching for a keyword that is capitalized, only those files that contain uppercase letters will be found in the search results. For example, if you are interested in Chinese-related documents, capitalize the letter of China, and use a more sensitive search engine in uppercase letters, the results of which will not have the documents on porcelain, utensils. If you want to get a better search result, it's generally not good to capitalize on it.
Third, phrase search
When searching for multiple words in a certain order in a keyword, enclose them in quotation marks so that the search results are files that fully match the query criteria. For example, if the search control law, using "control" as the keyword, search results are fully contained in the control of the file. However, if you do not enclose the keyword in quotation marks, the search results appear to contain or control a single keyword of the file, may be completely related to the control of the topic.
Four, abbreviation
If you're looking for information on gardening (gardening), you can use it as a keyword. However, if your search results are limited in number (though not necessarily gardening-related), and you want to expand your search, use the main part and the asterisk (garden*), and the search results will include "gardens, garden, gardener, Gardeners "and so on.
V. Boolean logic
Qualifying search criteria may be the most important feature, and Boolean provides you with a useful search engine logic. Boolean and, or, not (or the and not in some search engines), NEAR and parentheses are in many ways like computing a complex mathematical equation. This is what a Boolean is going to do for you.
Vi. and
If you want to include all the keywords in the search results, use uppercase and in the keyword, and the search results will include these two words. For example, search for 49ers and schedule, the search results are consistent with these two keyword files. Note: Be sure to capitalize each letter of and, or the search engine will think it is a keyword.
If the oval on the left represents all files including 49ers, the right oval represents all files including schedule, the cross section of the ellipse, and the green Place, representing all the files that contain the two words. You will see that this is helpful for narrowing the range of search results.
