PS.
4. I’ve found one more option – Theme search bar replace
– but in this case I can not type, by clicking search bar hides…
Pls give me any suggestions…
+ I thought, I could replace search results also without theme styles changing, I setted “Override the default WordPress search” to “ON” in “main search” instance, then tried to exclude one random post from results in plugin options, after I tried to search this post with default search, but it is still in results…
