I have a question about a field that is indexed, but not stored (as shown)
@Field(name = "empName", index = Index.UN_TOKENIZED, store = org.hibernate.search.annotations.Store.NO)

When I browse through the Lucene documents using Luke, I cannot see this field since it is not stored in the document. But I can search using it, since it is indexed. So that means the untokenized value is somewhere in the index. Where is this indexing information kept if it is not part of the Lucene document?

Thanks,
Seema

Hi Seema,

I think that the field isn't shown in Luke's Documents tab does not mean that it's not part of the index. Just click on "Reconstruct & Edit". Then you should see all fields -- the ones that are not stored are marked as "restored from index".

Greetings,
Joachim

Of course these values are somewhere in the index. The question is in which form and how easy it is to get to them. If you want to access your index data after a search using the Lucene Document you have to explicitly store the information. Otherwise the values just get indexed and become part of the inverted index which is the data structure for searching. I recommend you refer to the Lucene website in case you want to know more about the index data structures.
