Detektivo and layout

Hi, I’m using Detektivo with TNTSearch. I’m trying to index content in collections with a layout-grid field, but searching doesn’t return anything (searching on other collections with text fields works correctly.)

Has anyone had the same issue, and is there a fix for it? Would using a different search engine help? Thanks.

I switched to Algolia, and the layout-grid elements are being crawled properly.
