Hi ! I make a search and get the hits. this hits have lucene records say r1, .... rn. eache record has the fields f1 , f2 ... fn . I need to get a sumary of field values ( like those ebay , and shopping.com do ) for example : values for field f1 -> A :50 records B :60 records Others : 30 records (asuming the search produced 140 lucene documents. ) I really would apreciate if anybody knows how can I program that functionallity. I did it using a 'for' loop trough all the records , but it gets very slow when the amount of records is so large. Thank in advance for your ideas. -- View this message in context: http://www.nabble.com/lucene-question%28-summary-of-values-by-field-%29-tf4470515.html#a12746668 Sent from the Lucene - General mailing list archive at Nabble.com.
