Hmm, "it's complicated" ... but I assume searching titles for EACH %$term% is going to catch a lot of junk ( you may need some whitespace n that line "title LIKE '% $term %'" ( but that would run into issues if "term" is the start of end of the title... I suppose you could append leading/trailing spaces to the title (so this post would be " Problems with the search algorithm ")
.
similarly - if I search for "search algorithm" - you are finding all the titles with %search% and %algorithm% ... which will get "too many" results (versus searches "title LIKE '% search algorithm %' "
