Abusing mySQL

Today I'm abusing mySQL. Last week created a three table database, each table with about 8 000 000 rows, with lots of indexes.

Today, I'm creating two indirect indexes to, from words, find the sentences where they occurr. This will create an enourmous table, and I don't know if mySQL will like it. Then, I need to compare the efficiency of queries using 'LIKE' and queries using this auxiliary table.

Let us wait, and see....
