« first day (654 days earlier)      last day (1065 days later) »

Would perhaps opening a separate chat room related to Approach0 be reasonable? It seems that many users are testing it and they would be able to post there various searches and discuss their problems.
Another alternative (which I like less) would be using c-r-u-d-e for this purpose. I think that asking something about finding specific question would be perfectly on-topic in c-r-u-d-e. But this would be specific to this particular search engine.
When I try to search for $a\vee a$, the results are much closer to what I would expect.
