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

298 * In short, we keep around arrays of results that we expand as needed
299 * (and never shrink).
301 * static_token_results: this is where we append the results for each
302 * token within a given desktop directory, as we handle it (which is
303 * a union of all matches for this term)
305 * static_search_results: this is where we build the complete results
306 * for a single directory (which is an intersection of the matches
307 * found for each term)
309 * static_total_results: this is where we build the complete results
310 * across all directories (which is a union of the matches found in
313 * The app_names that enter these tables are always pointer-unique (in
314 * the sense that string equality is the same as pointer equality).
315 * This can be guaranteed for two reasons:
317 * - we mask appids so that a given appid will only ever appear within
318 * the highest-precedence directory that contains it. We never
319 * return search results from a lower-level directory if a desktop
320 * file exists in a higher-level one.
322 * - within a given directory, the string is unique because it's the
323 * key in the hashtable of all app_ids for that directory.
325 * We perform a merging of the results in merge_token_results(). This
326 * works by ordering the two lists and moving through each of them (at
327 * the same time) looking for common elements, rejecting uncommon ones.
328 * "Order" here need not mean any particular thing, as long as it is
329 * some order. Because of the uniqueness of our strings, we can use
330 * pointer order. That's what's going on in compare_results() below.
