Thanks for the prompt reply.
To clarify a few of your questions:
– My site is set to return products in search results, which works when Ajax Search is turned off.
– When I enable another plug-in called SearchWP, I get the results in the standard theme page, so it seems to be possible to use that layout with a different search than the default theme search.
You can access the site here:

Thank you so much for offering to take a look!
