Why can't the existing content be found by the search engine?

The information on the Internet is vast. In order to find the required information in the shortest time, we will use search engines to help. Currently, various search engines are constantly improving the search technology and expanding the search function, making it easier and more convenient to use. Even so, we often find that some content exists on the Internet, but you cannot find it using a search engine (this also includes the following situations: Although a lot of search results are obtained, but not the required information ). What is the cause of this situation?
Cause 1: Improper search engines are used for search.
To quickly retrieve useful results, you can use a suitable search engine to get twice the result with half the effort and avoid detours. The current social division of labor has become increasingly refined, and even search engines are no exception. Various professional and special search engines are constantly emerging. No search engine can cover all aspects, even the omnipotent Google will be helpless. But now many of my friends have this problem, that is, they just ignore the question of how they like to search directly using Google. They really regard it as a omnipotent "fairy drug ", in this way, chances of hitting the wall will naturally increase. In this case, Google itself is constantly growing and improving, because it is powerless in many fields.

Countermeasure: first, we should make a reasonable assessment of the content to be searched. Check whether the search information is uncommon. Do you need a dedicated search engine? When using popular search engines, consider whether the current search engine is applicable and whether to switch to other search engines to try again. In addition, you need to know more about the dynamics of the search engine and collect and sort it out.
Cause 2: incorrect use of search keywords
If you use the correct keyword, the search is half successful. There are two meanings of incorrect use of search keywords: first, they do not fully understand and understand the content to be searched, so that they are incorrectly used. For example, during the New Year, people everywhere say "dragon and horse spirit ", but what does Longma mean? If you don't think about it, you can directly use "what does Longma mean" as a search keyword in Google (except for the special instructions in this article, Google is used as a search engine, there will be meaningless results, but as long as you think about it, it seems that this question should be related to some allusions, and then use "Spring Festival dragon horse from" to search, then the first result is the answer; the second is to use the error code. If the keyword you are using contains an error, you cannot find the expected result accurately. Similarly, if the webpage author uses a typo, but you use the correct spelling method to search for it, you will not be able to get satisfactory results.

Countermeasure: first, you need to develop the habit of thinking, learn to analyze problems, and see which aspects of the content you want to search are closely related to, and then decide to use keywords. As for the problem of typos, although there is no particularly effective way, you can also try to look up the dictionary, think about the use of habits to speculate on common spelling methods to deal. If you think there should be a lot of online content, but you cannot find the results, you should first check whether there are any mistakes.
