Problems with search API v1 vs API v2

I have a # of posts that contain PDF attachments.  When I search for a phrase in the v1 API, if the phrase is in the PDF the message appears in the list

v1 url: https://community/community-id/restapi/vc/categories/id/[id]/search/messages?q=phrase

5 posts returned.

The v2 LIQL does not appear search the same way, and does not return the messages with PDFs.

v2 LIQL: select * from messages where (subject matches 'phrase' OR body matches 'phrase' AND category.id = 'ID'

2 posts returned.

Is there an additional field I can use in the v2 LIQL?

Also the count v1 API does not return the correct count:

v1 url: https://community/community-id/restapi/vc/categories/id/[id]/search/messages/count?q=phrase

value of 1 returned
