      1. Add a document to a collection, something like {{ { "value": "123-X-1 Hello" }

        }}

      2. Add a text index on the value property
      3. Perform a text search with something like {{ { $text: \{$search: '"23-X-1"' }

      It’s my understanding that $text searches do not match partial words or phrases. However, when I am searching in my MongoDB with a text index, it is returning matches that partially match an ID-like search query, for example:

      This search:

      {{{ $text: {$search: '"23-X-1"' }}}}

      Matches this document:

      {{

      { "value": "123-X-1 Hello" }

      }}

      Especially since it is quoted, I’d expect it to not match, since the phrase "23-X-1" doesn’t appear isolated anywhere in the value, but only appears as a partial match of the greater phrase "123-X-1".
