Full text search is not reliable
Full text search is a very useful and important function for me but there are some problems with it.
I have met two problems many times:
1. The articles shown in the search results may not actually contain the keywords I entered, especially when the keywords are a small sentence or phrase. Is this because the sentence or phrase is not searched as a whole?
2. When I set some a little complex search conditions, the search process runs very slow and sometimes even jumps an error to interrupt the search process without displaying search results.
