How to get all documents of lucene index?

Question

I have created a lucene index .

I would like to get all documents that just according to a field sorting and no search terms!

Answer 1

Please specify q=*:* as a search term

Answer 2

The class MatchAllDocsQuery looks like what you need to retrieve all documents: https://lucene.apache.org/core/4_4_0/core/org/apache/lucene/search/MatchAllDocsQuery.html

Answer 3

I don't know your Lucene versions match but the answer at 1 may work for you. See 2 for another thread including another approach.

Is it possible to iterate through documents stored in Lucene Index?
