504 * token within a given desktop directory, as we handle it (which is
505 * a union of all matches for this term)

508 * for a single directory (which is an intersection of the matches

512 * across all directories (which is a union of the matches found in
515 * The app_names that enter these tables are always pointer-unique (in
516 * the sense that string equality is the same as pointer equality).
517 * This can be guaranteed for two reasons:
519 * - we mask appids so that a given appid will only ever appear within
520 * the highest-precedence directory that contains it. We never
521 * return search results from a lower-level directory if a desktop
522 * file exists in a higher-level one.
524 * - within a given directory, the string is unique because it's the
525 * key in the hashtable of all app_ids for that directory.

528 * works by ordering the two lists and moving through each of them (at
529 * the same time) looking for common elements, rejecting uncommon ones.
530 * "Order" here need not mean any particular thing, as long as it is
531 * some order. Because of the uniqueness of our strings, we can use
532 * pointer order. That's what's going on in compare_results() below.
