// just in case you want to see the text score

      When using text search, it seems that some phrases can be ignored. I am using phrase searches to perform a logical AND on several words, for example:

      $text: { $search: "\"cat\" \"publications\"" }

      ...to find results containing BOTH the words "cat" AND "publications". However, we found that with this example the phrase "cat" seems to be ignored and the search seems to just return results matching "publications".

      See the repro steps for a simple example to demonstrate the issue.
