465 * token within a given desktop directory, as we handle it (which is

478 * This can be guaranteed for two reasons:
480 * - we mask appids so that a given appid will only ever appear within
481 * the highest-precedence directory that contains it. We never
482 * return search results from a lower-level directory if a desktop
483 * file exists in a higher-level one.
485 * - within a given directory, the string is unique because it's the
486 * key in the hashtable of all app_ids for that directory.
488 * We perform a merging of the results in merge_token_results(). This
489 * works by ordering the two lists and moving through each of them (at
490 * the same time) looking for common elements, rejecting uncommon ones.
491 * "Order" here need not mean any particular thing, as long as it is
