Although the search that comes with WordPress can search for some things, sometimes the search results are not necessarily satisfactory, and there is no joint search or fuzzy search, so sometimes you have to specify accurate keywords to get the search results. Moreover, the search that comes with WordPress relies heavily on MysqL database queries, which can be time-consuming if the database is large.

I have always been concerned about the "weak" search function that comes with WordPress. The search results are not very relevant and the results are not accurate enough. Moreover, the search function that comes with WordPress cannot search tags, categories, and other content. The search results can be listed in chronological order. Sometimes it is really troublesome to find things.
