Interesting; my experience has differed: I noticed since late 2022 (last year) Youtube Search was essentially ignoring my exact queries, giving only the first two or so result matching the query - the rest of the results aren't even marginally related.
Worse--this behavior continues, and has gotten so bad that today searching is all but useless to me.
FYI- Your portal gave me good laugh on how it finds 'exact' Titles: https://www.youtube.com/results?search_query=+intitle%3Afugi...
It works!
