Save a search as a view
If you want to search on top of another search, try saving your search as a View. Then, you can use the saved View as a data source for a new search.
This procedure walks you through creating a View from a search. To create a View from a search:
Start a new search, or edit an existing visualization from a Pinboard.
Any filters or aggregations created during this search will be reflected in the View.
Make any changes to the visualization that you want in your saved View (change aggregation level, filters, etc.)
Click the More menu icon , and Save as view.
Give the View a name and save it.
At this point the View has been saved, but you may also want to materialize the View, to improve its performance when searching.
