417 * static_token_results: this is where we append the results for each
418 * token within a given desktop directory, as we handle it (which is
419 * a union of all matches for this term)
421 * static_search_results: this is where we build the complete results
422 * for a single directory (which is an intersection of the matches
423 * found for each term)
425 * static_total_results: this is where we build the complete results
426 * across all directories (which is a union of the matches found in
429 * The app_names that enter these tables are always pointer-unique (in
430 * the sense that string equality is the same as pointer equality).
431 * This can be guaranteed for two reasons:
433 * - we mask appids so that a given appid will only ever appear within
434 * the highest-precedence directory that contains it. We never
435 * return search results from a lower-level directory if a desktop
436 * file exists in a higher-level one.
438 * - within a given directory, the string is unique because it's the
439 * key in the hashtable of all app_ids for that directory.
441 * We perform a merging of the results in merge_token_results(). This
442 * works by ordering the two lists and moving through each of them (at
443 * the same time) looking for common elements, rejecting uncommon ones.
444 * "Order" here need not mean any particular thing, as long as it is
445 * some order. Because of the uniqueness of our strings, we can use
446 * pointer order. That's what's going on in compare_results() below.
