As of now, the messages are retrieved entirely by the adapter before any filter by field can be applied.
This was changed in last trunk updates. Now selecting rows with a subset of columns (i.e: using a list of fields) can reduce the total payload retrieved. Queries not including fields like .attachments, .size, .email or .content will be much faster
