Sage is a general purpose theme, so yes, it should be fine.
But the WPSOLR Ajax template is deprecated.
WPSOLR will instead replace the WP_Query with Solr/Elasticsearch in the background, and your theme search template will display results as usual.
And yes, WPSOLR has an option to add Ajax responsiveness to your theme search.
