I'm looking for a way to allow a user to search 'within' current Solr search results (not search api solr results).
Is there existing functionality that provides this?
If I need to implement a module to do so, so be it; recommendations for what hooks to implement in that case would also be helpful.
Re. amateurbarista's comment. I'm wondering if there is a way to make a second query against the results of a first. I don't think Facets allow me to do this, is that so?
For example suppose my first search query returns 10 nodes. I'm asking what it would take to allow a second query to search only within those 10 nodes.
