5386 // The Receiver obtained from this function returns matches sorted by buffer path. Files without a buffer path are reported first.
5387 //
5388 // It gets a bit hairy though, because we must account for files that do not have a persistent representation
5389 // on FS. Namely, if you have an untitled buffer or unsaved changes in a buffer, we want to scan that too.
5390 //
5391 // 1. We initialize a queue of match candidates and feed all opened buffers into it (== unsaved files / untitled buffers).
5392 // Then, we go through a worktree and check for files that do match a predicate. If the file had an opened version, we skip the scan
5393 // of FS version for that file altogether - after all, what we have in memory is more up-to-date than what's in FS.
5394 // 2. At this point, we have a list of all potentially matching buffers/files.
5395 // We sort that list by buffer path - this list is retained for later use.
5396 // We ensure that all buffers are now opened and available in project.
5397 // 3. We run a scan over all the candidate buffers on multiple background threads.
5398 // We cannot assume that there will even be a match - while at least one match
5399 // is guaranteed for files obtained from FS, the buffers we got from memory (unsaved files/unnamed buffers) might not have a match at all.
5400 // There is also an auxilliary background thread responsible for result gathering.
5401 // This is where the sorted list of buffers comes into play to maintain sorted order; Whenever this background thread receives a notification (buffer has/doesn't have matches),
5402 // it keeps it around. It reports matches in sorted order, though it accepts them in unsorted order as well.
5403 // As soon as the match info on next position in sorted order becomes available, it reports it (if it's a match) or skips to the next
5404 // entry - which might already be available thanks to out-of-order processing.
5405 //
5406 // We could also report matches fully out-of-order, without maintaining a sorted list of matching paths.
5407 // This however would mean that project search (that is the main user of this function) would have to do the sorting itself, on the go.
5408 // This isn't as straightforward as running an insertion sort sadly, and would also mean that it would have to care about maintaining match index
5409 // in face of constantly updating list of sorted matches.
