The biggest problem with the search is that it, like many other things in this game, is case sensitive. Title searches complete quite quickly, but again, you have to match the title's case exactly. The horrendous performance of searching entire journal entry texts, speaking only of the time to complete, would be far less of a problem if it would actually find the terms you were searching for without you having to match the capitalization exactly. The slow searches are still a problem, but the case sensitivity is by far more offensive.
