I’m having a similar issue with the search.
I hadn’t fully tested it after purchasing (as I assumed it would work with product tags – schoolboy error I know)
So I checked the forum to see if anyone else had a fix and saw that Relevancci might be the solution…with a code snippet…
BUT – it doesn’t seem to be working if I type the tag name…with the ajax auto search…but if I click the spyglass icon it does (the other thing is, it displays the products as a blog archive page)
…would be so much nicer if the search query included any taxonomy (including tags for both blogs and products).
…equally, it would be EVEN BETTER if the results could differentiate from what is a blog post and a product and display the result in the correct format set in the XStore core?
I’m having the same issue with 2 dev sites on 2 different servers using the same version of XStore but different demo/template styles.
