Hello All,  
I am using libcurl to retrieve my indexed results. I have problems  
with the following code.  
[http://pastebin.com/NgdTBTAb](http://pastebin.com/NgdTBTAb)

The same code with out "to" in the range query seems to work fine. [code  
here: [http://pastebin.com/DYi10upZ](http://pastebin.com/DYi10upZ)]  
I tried its curl variation (below) and it seemed to retrieve all the  
results.

curl -XGET [http://localhost:9202/\_all/\_search?pretty=true](http://localhost:9202/_all/_search?pretty=true) -d '{  
"size": 1000000,  
"query" : {  
"range" : {  
"snapshotTime" : {  
"from" : "2012-10-31T13:00:00",  
"to" : "2012-10-31T14:00:00"  
}  
}  
}  
}'

Is there something wrong with the way I am querying?  
In case if there is a better library (C/C++) that suits elastic search  
needs, do let me know.  
Thanks.

By problems in the first code, I mean, I don't get any results back. The  
total\_hits remain 0. However, its curl version works fine retrieving all  
the results.
