All Implemented Interfaces:

public class OneDimensionalDocIssueHitCollector
extends AbstractOneDimensionalHitCollector

A HitCollector that accesses the document directly to get the values for a field. This HitCollector has low memory usage (it iterates over the documents as neccessary), and is useful when you are doing a collection where there are a limited number of documents, but a large number of terms in the entire index.

collectWithTerms in class AbstractOneDimensionalHitCollector

Parameters:

docId - the doc id of the hit. This is an index into the overall directory reader.

terms - the terms for the fieldId for this document, pre-calculated so you may not need to call getDocument
