: 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?

Is there a work-around wherein I can send an OpenBitSet object?



JavaBinCodec (used by default by solr) supports writing arrays. you can 
getBits() from openbitset and throw them into the binary response

But how to throw? As a stream of bits?

getBits() return a long[]
add a long[] part to your response

rb.rsp.add(long_array, obs.getBits())

How to send an OpenBitSet object from Solr server?

2011-08-29 Thread Satish Talim
We have a need to query and fetch millions of document ids from a Solr 3.3
index and convert the same to a BitSet. To speed things up, we want to
convert these document ids into OpenBitSet on the server side, put them into
the response object and read the same on the client side.

To achieve this, we wrote our own RequestHandler and overwrote
the handleRequest method. Using this RequestHandler we do get the response
object but when we try to fetch the OpenBitSet we get an error -

Exception in thread main java.lang.ClassCastException: java.lang.String
cannot be cast to org.apache.lucene.util.OpenBitSet

The documentation at -
http://lucene.apache.org/solr/api/org/apache/solr/response/SolrQueryResponse.html

says that Other data types may be added to the SolrQueryResponse, but there
is no guarantee that QueryResponseWriters will be able to deal with
unexpected types.

Is there a work-around wherein I can send an OpenBitSet object?
