5922 // and the second phase that finds positions of all the matches found in the candidate files.
5923 // The Receiver obtained from this function returns matches sorted by buffer path. Files without a buffer path are reported first.
5924 //
5925 // It gets a bit hairy though, because we must account for files that do not have a persistent representation
5926 // on FS. Namely, if you have an untitled buffer or unsaved changes in a buffer, we want to scan that too.
5927 //
5928 // 1. We initialize a queue of match candidates and feed all opened buffers into it (== unsaved files / untitled buffers).
5929 // 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
5930 // of FS version for that file altogether - after all, what we have in memory is more up-to-date than what's in FS.
5931 // 2. At this point, we have a list of all potentially matching buffers/files.
5932 // We sort that list by buffer path - this list is retained for later use.
5933 // We ensure that all buffers are now opened and available in project.
5934 // 3. We run a scan over all the candidate buffers on multiple background threads.
5935 // We cannot assume that there will even be a match - while at least one match
5936 // is guaranteed for files obtained from FS, the buffers we got from memory (unsaved files/unnamed buffers) might not have a match at all.
5937 // There is also an auxiliary background thread responsible for result gathering.
5938 // 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),
5939 // it keeps it around. It reports matches in sorted order, though it accepts them in unsorted order as well.
5940 // 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
5941 // entry - which might already be available thanks to out-of-order processing.
5942 //
5943 // We could also report matches fully out-of-order, without maintaining a sorted list of matching paths.
5944 // 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.
5945 // 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
5946 // in face of constantly updating list of sorted matches.
5947 // Meanwhile, this implementation offers index stability, since the matches are already reported in a sorted order.
