Revision 869

Added by thorn about 17 years ago

search: added search_lang for use in search-form. Using DE, the search will search ä=ae,... (alternate spelling of german umlauts)
removed undocumented word-boundary search
search_path is now anchored to the beginning of link ("link LIKE '$path%'" instead of "link LIKE '%$path%'")
added key 'ext_charset' to search-extension to query external databases
