20 - shows the screen to search forum posts (action=search), and uses the
21 simple version if the simpleSearch setting is enabled.
22 - uses the main sub template of the Search template.
23 - uses the Search language file.
24 - requires the search_posts permission.
25 - decodes and loads search parameters given in the URL (if any).
26 - the form redirects to index.php?action=search2.
27
28 void PlushSearch2()
29 - checks user input and searches the messages table for messages
30 matching the query.
31 - requires the search_posts permission.
32 - uses the results sub template of the Search template.
33 - uses the Search language file.
34 - stores the results into the search cache.
35 - show the results of the search query.
36
37 array prepareSearchContext(bool reset = false)
38 - callback function for the results sub template.
39 - loads the necessary contextual data to show a search result.
40
41 int searchSort(string $wordA, string $wordB)
42 - callback function for usort used to sort the fulltext results.
43 - passes sorting duty to the current API.
