Here is how you can do quick search in your JIRA directly from the browser url in Opera:
Go to Tools/Preferences/Search and add the following:
Name: Hibernate JIRA Keyword: h Address: http://opensource.atlassian.com/projects/hibernate/secure/QuickSearch.jspa Query String: searchString=%s Use POST: true
Name: JBoss JIRA Keyword: j Address: http://jira.jboss.com/jira/secure/QuickSearch.jspa Query String: searchString=%s Use POST: true
Now I can just enter "h hbx seam" to see hibernate jira issues for HBX that includes the word "seam"; and similar for JBoss but with a "j" as prefix.
If anyone can tell how I get the same functionallity in Firefox then it would be great (note: I know you can add custom searches to the firefox search field; what I'm asking for is the "enter string in URL line and get a custom search executed"-feature)
Update: Just saw this article which describes "Add Keyword for this search" popup menu in FireFox - same functionallity, but actually easier to configure (touche!)
Double update: Opera actually have a "Create search" popup menu too - I guess it's even functionality wise (but Opera had it first ;)
