This section describes the seven low-level mistakes that Cainiao are prone to when searching. It is precisely because you often make these mistakes that you always get useless, absurd, or meaningless search results. Once you realize these mistakes, it is easy to evict these moles from your search toolbox forever.
1: deprecated word Sputtering on ''Stop word''
========================================================
Some search engines ignore these words. When you enter the deprecated words into the search box, no matter how many related files are on the Internet, they will not be returned to you.
These are called "stop words" because the search engine does not search for these words in its database.
Why not search? Because deprecated words may be too common to be able to search for meaningful results, or the adverbs, hyphens, and prefixes in languages, it is also a variant of ''be'', such as is, are, were, been, and other meaningless words, unless they are in a phrase and have important nouns and verbs.
If you use deprecated words in a search request, you get a large number of irrelevant search results. For example, the phrase ''searching the web'' contains two stop words: ''The ''and ''web ''. Although this is not a very common word, the Web is too common on the Internet, so that it actually cannot help you find any useful content.
If you remove the deprecated word, ''searching the web'' is changed to ''searching''. the search results returned by this keyword will start from searching for a fugitive until you seek enlightenment. (Quests for enlightenment)-If you are lucky enough, you will also get some search results about "searching the Web.
How can we identify deprecated words? The 300 most commonly used English words are mostly deprecated words. When google contains deprecated words in your search keywords, it will tell you every deprecated word it ignores, it is displayed at the top of the search result page. You can use a keyword containing the deprecated word ''web'' to try it out.
2: Boolean operator Bungling with Boolean
============================================
Boolean operators, such as and, or, and not, can make your search results more accurate-if correct.
The problem is that the Boolean operator seems too simple and easy to use, which may be a misunderstanding.
According to Ran Hock, author of The "The Extreme Searcher's Guide to Web Search Engines", various Search Engines have their own support methods for Boolean characters, not exactly The same. For example, for the same effect, some search engines only use ''not'', but some search engines use ''And not. In addition, some search engines require that Boolean characters must be in uppercase, while others do not.
