One property with mapping "type": "string" and value "ReadingWonders2.0" is causing inconsistent query results.  
It seems to be analyzed inconsistently. When I query using match, I get a different number of hits each time I run the query.

If I use a term filter for both the original string and what \_analyze reports is the tokenized string, I get consistent results (same hits count each time I run the query) so it seems that some documents are being analyzed one way, and some the other...

**query returning inconsistent results:**

```
{
  "query": {
      "match": {
          "edApp.name": "ReadingWonders2.0"
      }
   }
}

```

hits.total values when running query multiple times: [44, 56, 57, 69]

**term query returning inconsistent results:**

```
{
    "query": {
        "bool": {
            "should": [
            {
                "term": {
                    "edApp.name": "ReadingWonders2.0"
                }
            }
            ]
        }
    }
}

```

hits.total values when running term query multiple times: [21, 33, 34, 46]

**Other term query returning inconsistent results (note lower case):**

```
{
    "query": {
        "bool": {
            "should": [
            {
                "term": {
                    "edApp.name": "readingwonders2.0"
                }
            }
            ]
        }
    }
}

```

hits.total values when running term query multiple times: [44, 56, 57, 69]  
NOTE: these are the same counts we saw with the match query!

**query with both terms:**

```
{
    "query": {
        "bool": {
            "should": [
            {
                "term": {
                    "edApp.name": "readingwonders2.0"
                }
            },
            {
                "term": {
                    "edApp.name": "ReadingWonders2.0"
                }
            }
            ]
        }
    }
}

```

hits.total values are consistent: 79 results

_ **The combined hits from lowercase, and camelcase term searches add up to the total 79 documents.** _

Any ideas why the match query is not finding some of the documents?

I should add that there is a chance this is related to enabling doc\_values for other properties in my mapping. After that change is when this issue cropped up. Not sure how that would affect analyzed strings though, it may just be a red herring.

I discovered that dynamic mapping was creating [generated.edApp.name](http://generated.edApp.name) field as "not\_analyzed" "doc\_values": true

This seems to conflict with [edApp.name](http://edApp.name) and cause documents to get mapped wrong!
