When beginning a bulk issue change, I'm usually looking at the result of a filter, or search, then click on Bulk Change. When the Bulk Change is complete, JIRA takes me back to the results of the filter or search I was just looking at, and it usually ends up showing no issues.. So I see a message of "No matching issues found".

This is misleading, and made me think that several of my bulk changes failed. You should either show me a confirmation message that my issues were successfully changed/moved, or take me to a different page that doesn't show messages such as this, such as the browse project page.
