Wildcards with query_string query and custom analyzer

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:

    "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.

Can you please add setting of your custom analyzer. it will help to understand issue.
