If you have common searches that you run regularly, VSys lets you save the criteria (rules) of those searches for later use. Near the top, click on Load/save criteria, then on Settings. Click on Save, then name the search and click OK to save the current criteria. Use Load to re-load criteria that you've saved in the past.
If VSys security is enabled, meaning you log into VSys when you first start it up, VSys will remember your criteria separately from those of other users. You won't see the values saved by other people, and they won't see yours.
