Analyzer Tokenizer for Exact and Contains search on single field
I am a Solr newbie. Let's say we have a field with 4 records as follows: James James Edward James Edward Gray JamesEdward a. In Solr 3.4, I want an exact search on the given field for James Edward. Record 2 should be returned. b. Next on the same field, I want to check whether James is contained in the field, then records 1, 2 and 3 should be returned. Which standard analyzer, tokenizer can one apply on one single field, to get these results? Satish

How to send an OpenBitSet object from Solr server?
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? Satish
Re: Multiple Cores on different machines?
Chris, sorry for not being clear when I asked the question. We are still experimenting with Solr. We have 2 tables in Postgres that we want to migrate to Solr for faster query results. One index is of static data and the other related index would be of data that changes once or twice a month. Some are proposing a single (flat) index in Solr for both these tables. Others are suggesting 2 separate indexes on 2 different machines and using SOLRs capacity to combine cores and generate a third index that denormalizes the tables for us. Query on a flat index is extremely fast and we wanted to compare the results with separate indexes.
