The table contains about 40 MB of space. How much data are you attempting to index, and how large is your key_buffer? Jeremy -- Jeremy D. Zawodny | Perl, Web, MySQL, Linux Magazine, Yahoo!

indexing text fields possible?
Hi there, I am wondering if it would be anyhow possible to make a search on a mysql textfield faster. Right now the table contains 294000 entries and takes about 40 MB of space. Is there a way to apply a index with a resonable amount of disk space? I am also not so sure if I should use text or smalltext columns as the info may vary between 1 and 1000 chars. A query for LIKE 'test%' takes about 20 s right now.
