Saved searches provide a list of all searches saved by any user in the matter. Unlike search history, saved searches are visible to all users and thus shareable. Click on the search box to expand the search helpers. Choose Saved Searches to see all saved searches for this matter.
To save a search, run the search first, then click the Save Search link above the search box. Here, you can name the saved search, as well as limit the search to un-tagged documents only if desired.
To customize your saved searches, you may name/label them whatever you like!
Again, to access saved searches, click on the search bar. Select "saved searches".
