Why is each kana mora or each kanji character considered a separate word when searching? Here is an image of the rsults of me searching for
よろしく on meta. You can see that the first three results have the whole phrase, but after that, it picks up any question/answer that has any of the characters in it. If you look under the "Advanced Search Tips", it says you can use double-quotes to search for an exact word or phrase. This works fine for English text, but again fails for Japanese text.
This makes searching in Japanese worthless, especially on the main site. Is there something that can be done about this?
