Hi there! I have a index structure like this:
document_id some_text ..... when searching for some set of documents, there could be a case when several comments for the same document match the search criteria. In such case I need to get single hit for all such cases, in other word - perform a "group by"-like operation based on document_id. For example, if I have records 1 : 10 : some text here 2 : 10 : some another text here and the search string was "+some_text:some" - I need get only one hit for both these records (return only document_id). I know I could collect all hits and then filter them, but I need also paging functionality, so if I need to collect 1.000.000 hits into 50.000 of records - I need to traverse all 1.000.000 of records, put 50.000 of unique items into helper array, then get last page with 10 results - and it will take a lot of time. -- Eugene N Dzhurinsky --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
