A Gentle Reminder! Any Solution around this problem? Regards -Neeraj
Thank you for the reply, As you said Sure, just iterate over the first 100 entries in your Hits object It means before Iteration Lucene has already spent time and memory in finding all the 50k documents and sorting them, then i will retrieve 100 documents. Hence it is costing me a search for 50k documents + sorting of these 50k matching documents + retrieval of first 100 documents.. Right? But what i want is the way, to get the same result as per the above process but with not costing me to search and sort all 50K matching documents. is this possible? Many Thx! -Neeraj "Erick Erickson" <[EMAIL PROTECTED]> 08/05/2008 04:16 PM Please respond to java-user@lucene.apache.org To java-user@lucene.apache.org cc Subject Re: Paging & Sorting Sure, just iterate over the first 100 entries in your Hits object (or topdocs). If you're asking how to ignore 49,900 of your documents (that is, not even consider them at all), you're asking the impossible because you can't know whether to ignore those other docs unless you sort them first. If you're asking if you can get the 100 most relevant docs and then sort only those, then you should look at FieldSortedHitQueue. What you'd do is feed the top 100 documents into an instance of FieldSortedHit queue then read traverse the queue. If none of this applies, could you explain in a bit more detail?
