Does lucene 4.6 use Lucene41PostingsFormat for Postings.nextdoc() while executing the span queries?
When I am debugging the lucene 4.6 test cases for span queries, it is showing that for above nextdoc() call it is utilizing DirectPostingsFormat. My requirement is to run multiple span queries like "cat dog"~2 on 2 TB of index and I am worried about the performance as I have to collect all the docs in results. For better performance: Is there a better postingsformat to choose from while using span queries in solr 4.6 or solr4.7? Given that we have lot of formats to choose from. Does having termVectors=true or termPositions=true and termOffsets=true helps? If yes then, should I think about what to use as TermVectorFormat? Thanks, Gopal
