Solr question
Hi All: I am new to Solr and I am facing a question if solr would can be helpful in a project that I'm working on. The project is a client/server app that requires a client app to index the documents and send the results in rdf to server. The client needs to be smart enough to know when a new document has been added to a specified folder, index it and send the results in rdf/xml to the server. The server will be a web service which will parse the xml and store the metadata in the a database. The search will be conducted on the server and will return the results from the database which will be links to the documents on the client. The client , which is also running a webserver will take the request when the user clicks on the link to the document residing on the client. I believe lucene will be useful in this scenario and solr can be used as a web app. I would like to get any input on this architecture and would request any pointers if there is any app already doing something similar and how lucene/solr can be useful in this case. Thanks for your time. Best Regards Raghav Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs

So its going to be a client/server app where all the
documents will be stored on the client and only
metadata of those docs will be sent to the server.
That way server does not have to store any real
documents. Its an internet based application. Search
on the server will read the metadata for keywords and
send the request to all the clients that contain
documents with that keyword. We cannot store
everything on one client, all clients are different
machines distributed all over the world.

How will the client serve the documents stored locally
through a standard mechanism (like port 80) to send
documents to the server when the server requests the
documents ? The client will not open any special ports
for the server, so we need the web server, I guess ?

The client application needs to give the users an
ability of handling metadata of the documents that
will be sent to the server so that efficient searching
can be conducted, so I assume we need a web app like
solr (or create our own using lucene).
Let me know your thoughts and thanks again for your
reply !

Reusing lucene index file in Solr
Hi All: I have a simple question : How can we re-use an existing lucene index file (.cfs) in Solr and search on it in solr? I need to do this as the index is created on one machine(client) to be used by solr server for searching. The solr server will refer to this index file by some http url. We cannot store this index file on the solr server. Any thoughts will be appreciated ! Regards Raghav. Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs
Re: Reusing lucene index file in Solr
Hi Erik, Thanks for your response ! On Page 180 of Lucene In action, there is a reference for searching multiple indexes remotely using RMI. I am still trying to figure out how that works and if that would fit in our scenario. We have multiple client machines running a web server where the indexes will reside. Can the server running solr query these indexes remotely over http ?

Converting lucene index into solr usable xml
Hi All: How can we convert the lucene index file into format that solr can understand. I have very little knowledge about solr and not sure if there is a way we can post the .cfs index file directly to the solr server with this command :- java -jar post.jar ? I assume post.jar only takes xml documents ? Any help would be appreciated ! Regards Raghav Looking for last minute shopping deals? Find them fast with Yahoo!

Re: Reusing lucene index file in Solr
Hi Yonik, Thanks for reply ! Once we have exported the index file on the server where Solr is running, how can we configure solr to use that index file and search on it ? In short, how does solr search on java lucene indexed files ? I am very new to Solr and am still trying to learn the basics. Since there is no proper documentation on solr, this mailing list is my only hope.
