So when you do the triage relevant-not-relevant, you would want to discard the non-relevant hits from the hit list, by pressing the 'delete' button, in order to visually narrow down that list to an acceptable format (original length perhaps 80 hits, length after narrowing the list down perhaps 12 hits) - some search tools I trialed did NOT react to the deletion button though, while it's evident that this would have been very important functionality.

It's odd that nobody except for me ever mentioned this lack of functionality of some (/all?) search tools: When you have got some 'hit list' (with or without indexed search), and when then you visually check the results, one by one, discarding the not-relevant hits by just reading their 'context-line' in the hit-table, or needing to look into the preview for that, or even needing to open the respective original files before discarding those files/hits as irrelevant for your current purpose.

in order to get half-way-neat search results, instead of then checking much too many search results visually, which time-wise would probably be the same nuisance but which is even less fun, for the following reason: Reading this request, I had hoped that someone came by with a solution by one of the indexing search tools - rjbull correctly mentioning FL Pro (50$) which does this indeed, but if you need this functionality for searching within gigabytes of data, FL isn't the right tool, except for special, not regular use cases, ie when you're willing to wait, and wait, and wait.
