Subject Re: How to send an OpenBitSet object from Solr server?
Date Thu, 01 Sep 2011 23:43:42 GMT

: I was not referring to Lucene's doc ids but the doc numbers (unique key)

Uh ... ok.  this is why i asked you waht you were planning on doing with 
the OpenBitSet -- it's just bits, indicating hte offsets of the documents 
in the total index.  having access to a copy of that on the lcient side 
isn't going to give you any info about the value of the uniqueKey field.

Like i said ... XY Problem ... please tell us what you overall goal is.  
why do you want the uniqueKey values for every matching doc in your remove 
client?  What would you do with the OpenBitSet from solr if you had a copy 
of it?
