Can I get the search engine query strings using javascript?

[shrirch]

I'd like to capture the search engine refferer string and populate my own search box with the string. Are their any widely available scripts that can do this?

I've got a very fast moving forum and have found that quite a few topics move out of the pages that have been craweled.

Any tips would be appreciated.

You can get the referrer using

document.referrer

Extracting the search value should be just a matter of using a regexp or other string functions on that variable.
