When I want to search for multiple words …

… it is suggested to add “AND” in between to search for both words at once. 

But if I do that, it doesn’t actually search for both words together, it just treats AND as another search word and delivers dozens of posts containing the word “and”. 

Where is it you are seeing this? I ask as that looks like our community, however I cant replicate it doing that my end.

Edit: Oh, actually I think I know what you mean here. These are clickable items. So you Would click and it would search using AND

A bit counter-intuitive, but okay, I now understand how to do it. 

No problem. This is so you can actually search for the word and if your system is allowing 3 letter searches
