Hi all,

I am using boolean queries to retrieve index entries, setting the size  
param to a preset resultset size.  
When the matching documents are less than the preset max, I get duplicate  
results to match the "size" requirement.

This is how I build the query:  
String json =  
"{"fields":["url","tv"],"size":"+Urls.size()+","query":{"+  
""bool":{"+  
""must":["+  
"{"term":{"eid":"+eId.toString()+"}},"+  
"{"term":{"cid":"+cId.toString()+"}},"+  
"{"terms":{"url":["url1","url2",...,"urlN"]}}]}}}"

Is there a way to retrieve unique results?

thx in advance,  
Dionysis
