Re: returning message to sender
David Smiley and Eric Pugh wrote a wonderful book on Solr: http://www.lucidimagination.com/blog/2010/01/11/book-review-solr-packt-book/ Reading through this book and trying the examples will address all of your questions.

Re: returning message to sender
Hmmm, this is a little murky I'm inferring that you believe that DIH somehow queries the data source at #query# time, and this is not true. DIH is an #index time# concept. DIH is used to add data to an index. Once that index is created, all searches against are unaware that there were different data sources. So, with a single Solr schema, you can use DIH on as many different data sources as you want, mapping the various bits of information from each data source into your Solr schema. Searches go against fields defined in the schema, so you're automatically searching against all the databases (assuming you've mapped your data into your schema) If I've misunderstood, perhaps you can add some details?

RE: returning message to sender
--=_Part_27114_30663314.1289327581322 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hi guys, I have been exploring Solr since last few weeks. Our main intension is to expose the data, as WS, across various data sources by linking them using some scenario. I have couple of questions. Is there any good document/URL, which answers... How the indexing happens/built for the queries across different data sources (DIH)? Does the Lucene store the actual data of each individual query or a combination?, where, if yes? Whenever we do a query against built index, when exactly it fires the query to database? How does the index get the updates from the DIH, For example, if my query includes 3 DIH and What is the max number of data sources, I can include to get better performace? How do we measure the scalablity? Can I run these search engines in a grid mode? Thanks. -- View this message in context: http://lucene.472066.n3.nabble.com/Storage-tp1871155p1871155.html Sent from the Solr - User mailing list archive at Nabble.com. --=_Part_27114_30663314.1289327581322 Content-Type: text/html; charset=us-ascii Content-Transfer-Encoding: 7bit Hi guys, I have been exploring Solr since last few weeks.
