Hi guys:  
There is a mistake here about elasticsearch1.7.5 :  
{  
"error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[EklIxB3jTH2gBt6-sjT6wA][i\_dsrhx][0]: ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData]}{[yro95n9hSsaROrA1oPCOTQ][i\_dsrhx][1]: RemoteTransportException[[node39][inet[/172.16.32.39:9300]][indices:data/read/search[phase/query]]]; nested: ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData]; }{[SPXGeONTROGMG2poPJkq8w][i\_dsrhx][2]: RemoteTransportException[[node38][inet[/172.16.32.38:9300]][indices:data/read/search[phase/query]]]; nested: ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData]; }{[9jUAFgprR1GO2xXw0\_fXRw][i\_dsrhx][3]: RemoteTransportException[[node220][inet[/172.16.32.220:9300]][indices:data/read/search[phase/query]]]; nested: ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData]; }]",

The mapping is {

Could you reproduce it with a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). Please, try to keep the example as simple as possible.

Would be better to reproduce on a recent version as 1.7 is not supported anymore.
