You're right, rereading my own post, I should've been more specific about what I mean by search, where I'm performing the search, etc. Your assumption is correct, I
am referring to the right-click > Search menu.
The options presented here will firstly depend on which view you are using.

The search options provided will depend on which column you right-click on
Holy hell that was not obvious at all but thank you for enlightening me. Thing is, I'm actually searching from the "playing tracks" panel. You're totally right: if I right-click specifically over the (fairly small) title text, "Find title" is always there. Since left-clicking anywhere on the track highlights the whole entry (title, genre, artist, etc.), I assumed it doesn't matter where inside the entry I click.
(As a sidenote, this might honestly be a case of the XY problem. I dragged a bunch of files from outside my usual music library into the playing tracks queue and wanted to listen through them. I already have some of the tracks in my library, so I wanted a quick way to check whenever I hear something familiar)
(I think this post probably belongs in questions as I don't see a bug)
I thought it was a bug because the "Find title" option appearing as an entry seemed entirely random. After your guidance I now understand it's not random and why it seemed that way. So, while not really a bug, I still think search options shouldn't depend on where inside an individual entry you click when the entry gets treated as a singular bit in the UI (e.g. highlighted upon left click).
At the very least I think something as basic as "Find title" should always be shown, just like "Find artist."
