I'm trying to run this query on ES 5.4:

```
POST /_search?pretty&size=500
{
"query": {
	"bool": {
		"must": [
			{
				"match": {
					"tags": "MY_TAG"
				}
			},
			{
				"range": {
					"timestamp": {
						"gt": 0,
						"format": "epoch_millis"
					}
				}
			}
		]
	}
}

```

(If it's not obvious, the document should have the tag `MY_TAG`, and the timestamp of the document should be greater than 0 (i.e. document should be created after this timestamp))

If I have either the match tag condition or the timestamp greater-then condition, the search returns something. However if I have them both together, the search returns an empty set. Does anybody know what I'm doing wrong?
