Description

Describe the bug Searching a query containing a phrase search like "the soup of the day" when having stop words in the settings like ["of", "the"] will never return any document, even if some documents exactly match the query.

To Reproduce See the below discussion: https://github.com/orgs/meilisearch/discussions/793

Meilisearch version: v.1.12.7

Potential Fix See the below comment containing a part of the solution: https://github.com/orgs/meilisearch/discussions/793#discussioncomment-11967148
