   > @roedoejet `json` indexes basically don't have any support for the `$in` operator today - they require some kind of range query in the selector in order to use an index.
   > 
   > One option is to install the [text index plugin](https://docs.couchdb.org/en/master/ddocs/search.html), which will give you native `$in` support via Lucene indexes.
   
   OK, thanks for this. I would love to see this documented [here](https://docs.couchdb.org/en/2.2.0/api/database/find.html#condition-operators). There is already a note about the regex operator not accepting indices, so I assumed that was the only operator to note wrt indices.
   
   What about my example with `$or`?
