I need to check whether the given filed value string contain word call 'select'

Ex : field request return following result  
[www.abc.cc/posts/page?v=8%20select%20all](http://www.abc.cc/posts/page?v=8%20select%20all).....

So I need the correct elasticsearch syntax to track result which are having word called 'select' in request field in the elasticsearch indexes.

I have tried following syntax, but it return an error

.....  
"filtered": {  
"query": {  
"query\_string": {  
"default\_field": "request",  
"query": "select OR SELECT"  
}  
},

.....
