描述

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

研究方向
Start by reading the linked discussion (https://github.com/orgs/meilisearch/discussions/793) and the comment with a potential fix (https://github.com/orgs/meilisearch/discussions/793#discussioncomment 11967148). Examine how stop words are handled in the search indexing and phrase search logic, likely in the `milli` crate. Focus on the interaction between stop words filtering and phrase query parsing. No existing PRs are linked, so this is open for contribution.
