Lucene Pagination with Query

Yogesh patel
Hi

I have index 100000 documents in Lucene. I have one query that gets all
documents and it takes more time..
So i need to implement paging in lucene query so i can search result fast
page wise.

Is it possible to do paging or smart rendering with Lucene.

Awaiting for reply.

Yes.You can use the method:

publicTopFieldDocs  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/TopFieldDocs.html>  search(Query  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/Query.html>  query,
                   Filter  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/Filter.html>  filter,
                   int n,
                   Sort  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/Sort.html>  sort)
                     throwsIOException  <http://download.oracle.com/javase/1.5.0/docs/api/java/io/IOException.html?is-external=true>

see the api at http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/IndexSearcher.html

That method is for your situation.See the javadoc api for more details.

publicTopDocs  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/TopDocs.html>  searchAfter(ScoreDoc  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/ScoreDoc.html>  after,
                   Query  <http://lucene.apache.org/core/3_6_0/api/core/org/apache/lucene/search/Query.html>  query,
                   int n)
                     throwsIOException  <http://download.oracle.com/javase/1.5.0/docs/api/java/io/IOException.html?is-external=true>
