I found the sort by relevance and date. Would like to see the date listed for each item. Will help to decide what to look at. Usually I am looking for more recent posts then older posts.
Also with the Date sort, I can't tell how it is sorting unless I click into a post. Oldest first or newest first. I see the arrows on the button, still doesn't always click in the brain as to how the sort is working. Dates would help any confusion.
On relevence, is the database calculating a percentage? It is calulating some number so it can perform the sort. Can that be shown as well?
