@th3darknight , if you need any specialized search, let me know, because my page probably can solve your problem:
fbserv.herokuapp.com/games.htmlIt uses Javascript both as a selection criterion, and as an aggregation function ( for example it can calculate averages over selected games, etc. ) . In a sense it is allmighty, because it can search anything that can be searched based on lichess game JSON representation. Drawback is that there are no user friendly shortcuts as in lichess search. So you have to be familiar with both Javascript and lichess game object to be able to use it.
