[SQL] Very slow search using basic pattern matching

[Dan Field]

<x-tad-bigger>I'm trying to use the following statement as part of a search facility on a site I develop. However the search is taking in excess of 10 seconds some times to return results. I'ts a dual opteron server with a couple gigs of RAM so should be more than enough to deal with this database.


SELECT
da_records.RECORD_ID,
da_records.TITLE_EN AS TITLE,
da_records.AUTHOR_EN AS AUTHOR,
da_records.DESCRIPTION_CY AS DESCRIPTION,
da_records.PUBLISHER_CY AS PUBLISHER,
da_records.URL_CY AS URL,
da_records.RECORD_ID,
da_records.KEYWORD_LIST_ID,
da_records.LANGUAGE,
da_records.CONTRIBUTOR_NAME,
da_records.CONTRIBUTOR_EMAIL,
da_records.CONTRIBUTOR_ORGANISATION,
da_records.CONTRIBUTOR_CREDIT,
da_records.DEWEY_LIST_ID,
da_records.LISTING_PRIORITY,
da_records.SUBMITTED_DATE,
da_records.LAST_EDIT_DATE,
da_records.STATUS
FROM
da_records
WHERE
da_records.DESCRIPTION_CY ~* '.*Aberystwyth*.'
OR
da_records.TITLE_CY ~* '.*Aberystwyth*.'
limit 100

</x-tad-bigger>Is there a better way of matching the string? (Must be case insensitive)

TIA
