In the class QueryPhase.java  
When i use TopChildrenQuery in the line 153 i can't compare using  
topDocs.totalHits  
if (topDocs.totalHits \<= numDocs) {  
break;  
}

topDocs.totalHits have number os childrem match, need compare number  
os parents return.

Anybody have this problem ?

> I had one small problem when doing a search using TopChildrenQuery and realized …that when I have more than 51 children to the same document, my search has not returned any results. Digging deeper I found comparison what might be wrong in class QueryPhase.
