348 * We only ever search under a global lock, so we can use (and reuse)

351 * In short, we keep around arrays of results that we expand as needed
352 * (and never shrink).
354 * static_token_results: this is where we append the results for each
355 * token within a given desktop directory, as we handle it (which is
356 * a union of all matches for this term)
358 * static_search_results: this is where we build the complete results
359 * for a single directory (which is an intersection of the matches
360 * found for each term)
362 * static_total_results: this is where we build the complete results
363 * across all directories (which is a union of the matches found in
366 * The app_names that enter these tables are always pointer-unique (in
367 * the sense that string equality is the same as pointer equality).
368 * This can be guaranteed for two reasons:
370 * - we mask appids so that a given appid will only ever appear within
371 * the highest-precedence directory that contains it. We never
372 * return search results from a lower-level directory if a desktop
373 * file exists in a higher-level one.
375 * - within a given directory, the string is unique because it's the
376 * key in the hashtable of all app_ids for that directory.
378 * We perform a merging of the results in merge_token_results(). This
379 * works by ordering the two lists and moving through each of them (at
380 * the same time) looking for common elements, rejecting uncommon ones.
381 * "Order" here need not mean any particular thing, as long as it is
382 * some order. Because of the uniqueness of our strings, we can use
383 * pointer order. That's what's going on in compare_results() below.
