I am running the query as below in Elasticsearch. Even though there are multiple documents with the filter criteria matching available, I get an empty response. Any help is appreciated

{  
"bool" : {  
"filter" : [ {  
"range" : {  
"CREATE\_TIME" : {  
"from" : "2013-01-01T00:00:00.000Z",  
"to" : "2015-12-31T00:00:00.000Z",  
"include\_lower" : true,  
"include\_upper" : true  
}  
}  
}, {  
"range" : {  
"MODIFY\_TIME" : {  
"from" : "2013-01-01T00:00:00.000Z",  
"to" : "2015-12-31T00:00:00.000Z",  
"include\_lower" : true,  
"include\_upper" : true  
}  
}  
} ],  
"should" : [ {  
"match" : {  
"NAME" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 6.0  
}  
}  
}, {  
"match" : {  
"COL\_NAME" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 5.0  
}  
}  
}, {  
"match" : {  
"SAMPLE\_NAME" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 3.0  
}  
}  
}, {  
"match" : {  
"DESCRIPTION" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 2.0  
}  
}  
}, {  
"match" : {  
"SAMPLE\_DESCRIPTION" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 1.0  
}  
}  
}, {  
"match" : {  
"EXAMPLE" : {  
"query" : "Cat",  
"type" : "phrase",  
"boost" : 6.0  
}  
}  
} ],  
"minimum\_should\_match" : "1"  
}  
}

The Format of Timestamp is same in the index.

how about using keyword 'cat' instead of 'Cat'?  
Analyzed keyword is commonly lower character.

Might depends on your mapping.  
Can you provide it and a matching document?

Within a script would be even better.
