FieldSelector
Hi,
what kind of fields loads IndexSearcher.Document doc(int i)? Only those with
Field.Store.YES?
I'm asking because I do not need to load the tokens - should I use a
FieldSelector or are these fields not loaded?
Thank you

Yes, Lucene can only load those fields that are stored.

FieldSelector is used to selectively load fields that you want
returned with the document. The tokens produced by analysis are
stored in other places and will not be returned by the document()
method.

Depending upon the structure of your index, FieldSelector can
make a dramatic difference in your query speed. I wrote up
some data peculiar to my setup, I think if you search FieldSelector
on the Wiki you can find it.
Best
