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 Answer, or visualization from a Pinboard.
Any filters or aggregations created during this search become part of the new view.
Make any changes to the visualization that you want in your saved view (change aggregation level, filters, etc.)
Click the More icon , and select Create view.
Give the view a name and save it.
Link your view to any other data source, or define joins.
Your view is now saved. You may want to materialize the view to improve its performance when searching.
