Hi All, I was wondering - is it possible to search and group the results by a given field? For example, I have an index with several million records. Most of them are different Features of the same ID. I'd love to be able to do.. groupby=ID or something like that in the results, and provide the ID as a clickable link to see all the Features of that ID. I have used HitCollector class to accomplish this goal. In Collect method I have used following algo... Collect() { if Searcher.Doc(doc_id).get(ID) is not exist in HashKey then Add Searcher.Doc(doc_id).get(ID) as new HashKey in hash table and assign value = 1 else increment HashKey( Searcher.Doc(doc_id).get(ID)) value with 1 } But, it depends on HitCount. As soon as I get more hits it takes more time and my search performance is degrade. How it can be done with best performance..? Any ideas? Sawan
