28 * Display results of pagename search.
29 * Provides no own input box, just <?plugin-form TitleSearch?> is enough.
30 * Fancier Inputforms can be made using <<WikiFormRich ...>> to support regex and case_exact args.
32 * If only one pages is found and auto_redirect is true, this page is displayed immediatly,
33 * otherwise the found pagelist is displayed.
34 * The workhorse TextSearchQuery converts the query string from google-style words
35 * to the required DB backend expression.
36 * (word and word) OR word, -word, "two words"
37 * regex=auto tries to detect simple glob-style wildcards and expressions,
38 * like xx*, *xx, ^xx, xx$, ^word$.
