Workaround XF bug where a search type parameter was not validated as being allowed for a search handler
Workaround XF bug where a search could be constructed which targeted the parent (ie thread) content type and not the child (ie post) content type resulting in potentially degraded search results
Replace search/member search with a redirect to a standard search with the appropriate parameters entered. Stock XF member searches are slightly specialized and the general search is missing several features to support normal search being a strict super-set of member search.
XF lacked a "search only X" per search tab that this add-on injects
XF would target the parent type and didn't figure out the child type
Force a search without a query string to render it as * which allows member searches to be edited/refined
Redirect to XFES configuration page if XFES isn't configured instead of the search index list
Show basic statistics on the search index list page
