It would be nice to be able to filter out different sources. For instance, someone may have had a lot of bad experiences with oDesk so would rather not even see their postings.

Thanks for the suggestion!

It's possible to do the inverse right now, pick results from a particular source. Like you could search for "+php +facebook source:elance" (without quotes) to get php+mysql jobs results from elance.

You can also specify a budget with "minbudget:[number]" shorthand. It will search for all jobs with budget >= what is specified.

There's a third shorthand that lets you see only fixed-pay jobs or hourly jobs "type:[hourly OR fixed]".

Its all written down here http://www.grep42.com/faqs/. Perhaps I should make it more obvious?

EDIT: Sorry, the shorthand/filter "budget:[number]" should be "minbudget:[number]"

Maybe all that stuff could be put in the UI, perhaps with a javascript popout that has checkboxes, etc and then when the user enters the data, the code is injected into the search bar. Just an idea.

Hmm. One thing's for sure, it's gotta be click friendly. I'm thinking drag and drop, clicks, minimal typing..
