I have a `query_string` query I'm using with wildcards and a custom analyzer. The query behaves as expected for some words and not for others.

Here's the query:

```auto
    "query_string": {
      "query": "Abdulla*",
      "analyze_wildcard": true,
      "allow_leading_wildcard": true,
      "analyzer": "custom_common_grams_analyzer",
      "fields": ["text"],
      "lenient": true
    }
  }

```

When I use either `?` or `*` wildcards anywhere in the query term `Abdullah`, I get the expected results. `*bdullah`, `Abd?llah`, and `Abdull*` return all documents that contain `Abdullah`.

The query term `grandfathered`, however, doesn't work the same way. I get zero results if I use any `?` wildcards in the word. If I use a `*` wildcard I also get zero results, unless the `*` is in the last two characters of the word, and the number of results that come back differ if I use `grandfather*d` or `grandfathere*`. With `grandfathere*` I get back the full, correct set of results. My custom analyzer does incorporate stemming.
