Well, first I would suggest cleaning up your INSERT's; specify the column names in the query and omit columns such as AUTO_INCREMENT id's and whatnot.
Second, you'd just do a simple SELECT query with a WHERE clause to lookup the data. Example format:
SELECT foo FROM bar WHERE foobar = 'world'
EDIT: Also note that adding an index on the column you're searching (e.g. the word column) would help optimize the SELECT queries.
