We could start a list of examples, to help show editors what all is possible, and useful, with the new filter combinations.
E.g. I was looking at Enwiki's [[https://en.wikipedia.org/wiki/Special:Tags |Special:Tags]] and noticed the `#possible vandalism` tag. By itself it was not useful, because almost all the edits had already been reverted. But in combination with the filter for `Latest revision` it reduced the list down to [[https://en.wikipedia.org/w/index.php?hidebots=1&hidepreviousrevisions=1&hidecategorization=1&hideWikibase=1&tagfilter=possible+vandalism&limit=100&days=30&enhanced=1&title=Special:RecentChanges&urlversion=2 |a dozen or so diffs]] which I could easily go through.
That example isn't //great//, because even on the largest wikipedia it barely has any results, but it got me thinking that we should have a list of "examples of how editors/patrollers are actually using these filters".
I was thinking of https://wikitech.wikimedia.org/wiki/Help:MySQL_queries#Example_queries as inspiration (the page that Quarry links to for examples), where editors can add their own examples, and improve/organize them over time.
Similarly the drop-down list of Examples in https://query.wikidata.org/ which are taken from https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples
