If plugin's role is to extract - textual data from .doc, .pdf or .xml content, it might extract - plaintext from the content, and then pass the text to the default - MySQL parser to be parsed. - - mysql_add_word: A server callback to add a new word. When parsing - a document, the server sets this to point at a function that adds - the word to MySQL full-text index. When parsing a search query, - this function will add the new word to the list of words to search - for. The boolean_info argument can be NULL for all cases except - when mode is MYSQL_FTPARSER_FULL_BOOLEAN_INFO. - - ftparser_state: A generic pointer. The plugin can set it to point - to information to be used internally for its own purposes. - - mysql_ftparam: This is set by the server. It is used by MySQL functions - called via mysql_parse() and mysql_add_word() callback. The plugin - should not modify it. - - cs: Information about the character set of the document or query string. - - doc: A pointer to the document or query string to be parsed. - - length: Length of the document or query string, in bytes. - - flags: See MYSQL_FTFLAGS_* constants above. - - mode: The parsing mode. With boolean operators, with stopwords, or - nothing. See enum_ftparser_mode above. +/************************************************************************* + API for I_S plugin.
