peter ac53a3b757 perf(search): a one- or two-letter last word is matched whole, not as a prefix
A 1-2 letter prefix matched most of the library and ts_rank scored every
match: "m" took ~4-8 s on prod against ~150 ms now. The prefix match
starts at three characters (MIN_PREFIX_LEN); shared by the YouTube feed
and the Plex library search.
