I have found that the history search that ships with firefox works much better.
What firefox is missing is able to search the html content of web pages.
I've been trying recall monkey for a month now it hasn't got me a single hit.
Also for just an advanced search I dont get the use of prioritize/exclude
It may be that I am not using this correctly.
Prioritize/exclude promotes or excludes results from a set of (sub)domains that you can select. It does not index the page content, but it searches through titles and URLs. Try making sure you have a recent version, v21 is the latest.
