Hi.  
I am trying to find a way to express a character count filter in a  
querystring, for instance: I need to find all documents with field  
"subject" that holds less than 20 chars.  
How would i do that in a querystring ?

/David

You could use a script filter:

"filtered" : {  
"query" : {  
...  
},  
"filter" : {  
"script" : {  
"script" : "doc['subject'].value.length() \< 20"  
}  
}  
}

Well yes i know that one, is this really the only/best way to do it?.  
My application is forwarding an input field directly to a querystring, the  
user need to be able to query something like this:

tags:h1 AND subject:lenght\>20
