Hi. Maybe this will give you more options. It's my favorite MLS search site -- no selling, no signup, and you can manipulate the info extensively.
The site always defaults to its home page, so I can't give you a link directly to their Thurston County page. Here's how to get there:
Left side of page, under Seattle Home Search by City names
click on blue
Add More Criteria.
On the new page, under Search Type:
at City List for [All Counties] click on the little down arrow to the right of [All Counties] and click on Thurston County.
That will bring up a list of Cities and towns in that county.
Then below that list you can specify or eliminate all the details you want.
