solr index for multi-valued multi-type field

Question

I am indexing a collection of xml document with the next structure:

  1234
  Some Name
  

        

Answer 1

I think there is no obvious solution for indexing data coming from the many-to-many relationship. In this case I would go with dynamic fields: http://wiki.apache.org/solr/SchemaXml#Dynamic_fields

Field definition in schema.xml:

<dynamicField name="experience_*" type="integer"  indexed="true"  stored="true"/>

So, using your example you would end up with something like this:

<mydoc>
  <id>1234</id>
  <name>Some Name</name>
  <experience_Java>10</experience_Java>
  <experience_Hadoop>4</experience_Hadoop>
  <experience_Hbase>1</experience_Hbase>
</mydoc>

Then you can use the following query: fq=experience_Java:[3 to *]
