             Summary: Queries with offset are broken for iteration
                 Key: ISPN-2448
                 URL: https://issues.jboss.org/browse/ISPN-2448
             Project: Infinispan
          Issue Type: Bug
          Components: Querying
    Affects Versions: 5.2.0.Beta2
            Reporter: Ales Justin
            Assignee: Sanne Grinovero
             Fix For: 5.2.0.Beta3


The problem is with queries with offset when you iterate over them -- offset is never taken into account.

There are two possible fixes -- as I see them.

1) In HS:

DocumentExtractorImpl::extract takes into account "firstIndex"

	public EntityInfo extract(int scoreDocIndex) throws IOException {
		int docId = queryHits.docId( firstIndex + scoreDocIndex );
		Document document = extractDocument( fistIndex + scoreDocIndex );

2) LazyIterator in Infinispan-Query applies the offset:

  protected EntityInfo loadEntityInfo(int index) {
     try {
        return extractor.extract(extractor.getFirstIndex() + index);

---

Since those methods are exposed in DocumentExtractor,
I would guess they were meant for external code to use them,
instead of putting this logic into extractor itself.
