Doc in groups – Database

Hello everyone,

I’m developing a search engine for my buddy site and I’d like to include the buddypress docs. For this I need to check if a posted document has been posted in a group the logged user belongs to. But I can’t find in the database anything that links the document (in wp_posts or wp_postmeta) to the group it belongs to. In wp_bp_groups_groupmeta, there is only an entry that says that docs are enabled in the group but I can’t find the id of the docs inside.

Have you any idea of how to proceed ?

Thanks in advance
