Search broken?

[Russell]

Looks like the search function is no longer working today. When I try to search I get this:

Could not obtain matched posts list

DEBUG MODE

SQL Error : 1016 Can't open file: 'phpbb_search_wordmatch.MYI'. (errno: 145)

SELECT m.post_id FROM phpbb_search_wordlist w, phpbb_search_wordmatch m WHERE w.word_text LIKE 'test' AND m.word_id = w.word_id AND w.word_common <> 1
