Changes between Initial Version and Version 1 of Ticket #25585, comment 10

initial	v1
5	5	The idea is to remove single letter terms from the search. The pattern `/^\p{L}$/u` is the safest way to match a single letter in any language. It's not particularly fast as it looks through the Unicode character properties. A better (but quite slower) pattern could be `/^\p{L}\p{M}*\|\p{Z}\|\p{P}\|\p{C}$/u` which also matches separators (any kind of whitespace or invisible separators), punctuation, and invisible control characters and unused code points.

7		`search_terms_count` is the count before the terms were cleaned. It's used to determine if the sorting would use ~~AND and OR for the title, or just the~~ sentence match. This part of parse_search_order() has gone through quite a few changes, maybe there is a simpler way to do that now.
