I'm using Relevanssi to index my site because it includes custom fields and taxonomies in the index. When I use the search box on my site, the results include matches from custom fields, etc. but when I enter the same search query URL with "&json=1", the search results are empty.
I'm assuming that the JSON API is bypassing the Relevanssi search plugin and using the default WP search. How would I go about convincing the JSON API to use the custom search plugin?
