RE: Does Solr fit my needs?
Without speaking directly to the indexing and searching of the specific fields, it is certainly possible to retrieve the xml file. While Solr isn't a DB, it does allow a binary field to be associated with an index document. We store a GZipped XML file in a binary field and retrieve that under certain conditions to get at original document information. We've found that Solr can handle these much faster than our DB can do. (We regularly index a large portion of our documents, and the XML files are prone to frequent changes). If you DO keep such a blob in your Solr index, make sure you retrieve that field ONLY when you really want it... Now - if your XML files are relatively static (i.e. only change rarely, or only have new ones) then it still might make sense to use a real DB to store those, and just keep the primary key to the DB row in the Solr index.

Re: Does Solr fit my needs?
We have used both Solr and graph databases for our XML file indexing. Both are equivalent in terms of performance, but a graph db (such as Neo4j) offers a lot more flexibility in joining across the nodes and traversing. If your data is strictly hierarchical Solr might do it, alternately suggest looking at a Graph database such as Neo4j.

Re: Does Solr fit my needs?
Solr will not keep the structure of your XML data. Solr and Lucene have a flat data model. You can map hierarchy into that, but it can be a lot of work. I recommend starting with a dedicated XML database. MarkLogic is commercial, but they have added a free developer license that can be used for some production (see limitations here: http://community.marklogic.com/express). I would say to use an XML database, but there really is no other production-ready XML database. eXist is nice, but it can be 100X slower than MarkLogic. I used to work at MarkLogic and I've implemented Solr at two major web companies. If you really want to work in XML, you'll be a lot happier with MarkLogic. wunder On Apr 27, 2012, at 7:31 AM, G.Long wrote: Hi there :) I'm looking for a way to save xml files into some sort of database and i'm wondering if Solr would fit my needs.

Re: Does Solr fit my needs?
You could use SQL Server and External Fields in Solr to get what you need from the database on result of the query.
