When doing a contains match, split the words and perform an and on it.
2002-04-18 Not Zed <NotZed@Ximian.com> * camel-folder-search.c (check_header): When doing a contains match, split the words and perform an and on it. (match_words_messages): If we have an index, but were forced to do a full search, first lookup a subset of messages using the index and a simplified word set. Only do a manual search of this subset. 2002-04-17 Not Zed <NotZed@Ximian.com> * camel-folder-search.c (match_message_index): Changed to take a utf8 string not a regex pattern. (match_words_index): Matches against a camel_search_words list. (match_words_1message): Matches a single message against a camel_search_words list. (match_words_message): Same, but gets the message from the folder for you. (match_words_messages): Matches a list of messages against a words list. (search_body_contains): Rewritten to handle multiple word searches. For #23371. * providers/imap/camel-imap-search.c (sync_match): Split words when searching, to support multiple search words. Also, try searching specifying charset of utf8 if we can, if that fails, fall back to not specifying charset. TODO: It should translate the strings into the locale default charset? * providers/imap/camel-imap-store.c (connect_to_server): Added new cap - utf8_search, if set, we tell the server we're searching using utf8, otherwise we dont (incorrectly, since we always use utf8 to search). * camel-search-private.c (camel_ustrstrcase): Make this class public. (camel_search_words_split): Split a word into multiple words based on whitespace, and keep track of whether the word is simple (indexable directly), or not. (camel_search_words_free): Free 'em. svn path=/trunk/; revision=16501
