Our Index Intersection page (https://docs.mongodb.com/manual/core/index-intersection/) makes no mention of text, 2d or 2dsphere indexes.

I'm pretty sure that those indexes can't participate in index intersection because they are quite different from BTree indexes and are used via type specific functions like $text and $near. I wanted to point the user to a manual page that said that definitively, but there is no such place.

Another place this could be mentioned is on the 2dsphere and text indexes pages:

• https://docs.mongodb.com/manual/core/2dsphere/
• https://docs.mongodb.com/manual/core/index-text/
