I"ve implemented two main methods for that purpose: embedText and extractText. You can find the full and documented code with a running example attached to this tip.
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001499s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.113284s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.001022s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.001161s ]
SHOW FULL COLUMNS FROM `jrk_member` [ RunTime:0.000979s ]
SELECT `id`,`username`,`userhead`,`usertime` FROM `jrk_member` WHERE `status` = 1 ORDER BY `usertime` DESC LIMIT 10 [ RunTime:0.003144s ]
SHOW FULL COLUMNS FROM `jrk_searchrecords` [ RunTime:0.000973s ]
SELECT * FROM `jrk_searchrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 5 [ RunTime:0.003825s ]
SELECT aid,title,count(aid) as c FROM `jrk_downrecords` GROUP BY `aid` ORDER BY `c` DESC LIMIT 10 [ RunTime:0.016396s ]
SHOW FULL COLUMNS FROM `jrk_articles` [ RunTime:0.001146s ]
UPDATE `jrk_articles` SET `hits` = 2 WHERE `id` = 73680 [ RunTime:0.014155s ]
