Is “customid” a docValues=true field? I suspect not, in which case
I think this is the problem (but do be warned, I don’t spend much time in
Lucene code).
this.reader.document(docNumber).get("customid”)
document(docNumber)
goes out to do a disk read I think. If it were docValues=true, it could be
fetched from
the in-memory structures instead. I don’t know how much of that is automatic at
this
level though.
Best,
