Feature request: search by opening

See subject; it would be nice to have a feature in the advanced search where the results can be limited by opening.

For other people wanting this feature, I just found: www.openingtree.com which sort does the job for me. But still, it would be very nice for lichess to have a search by opening feature as well.

True

Advanced search.

#5what is this?

@Vertonghen, the point is that I would like to a drop-down box for example on the page you linked that allows selecting an opening (variant).
