With each search you have to sort out the garbage by selecting the category afterwards. Again and again!
All entries have no text preview. Now you have to guess by the title if the searched is meant and there is hardly any chance to get a hit at first sight, unless the title matches the question. The results are general, a bit of each, imprecise and unsorted. Looks like you think: a lot helps a lot!
Archived entries are no longer found even if they are still relevant.
