+plocate works by creating an inverted index over trigrams (combinations of
+three bytes) in the search strings, which allows it to rapidly narrow down the
+set of candidates to a very small list, instead of linearly scanning through
+every entry. It does nearly all I/O asynchronously using io_uring if available
+(Linux 5.1+), which reduces the impact of seek latency on systems without SSDs.
+Like mlocate and slocate, the returned file set is user-dependent, ie. a user
+will only see a file if find(1) would list it (all directories from the root
+have +rx permissions).
