> There is an issue with *org.apache.solr.handler.dataimport.DocBuilder:addFields* around ~line 643.  The logic currently says see if you can find the field from the schema, ie:
> {code:title=DocBuilder.java|borderStyle=solid}
> SchemaField sf = schema.getFieldOrNull(key);
> {code}
> and, if not found, go ask DIHConfiguration to find it, ie:
> {code:title=DocBuilder.java|borderStyle=solid}
> sf = config.getSchemaField(key);
> {code}
> The latter call takes into account case-insensitivity, which is a big deal since some databases, ie: DB2, upper case all the resulting column names.  In order to not modify solr-core (ie: the match logic in IndexSchema), I'm attaching a patch that makes DIHConfiguration apply the same case-insensitive logic to the DynamicFields.
> Without this patch, dynamic fields will not be added to the index unless you declare them like this:
> {code:xml}
>   <dynamicField name="*_S" type="string" indexed="true" stored="true" />
> {code}
> (note the capital S)
> which is in-consistent with what I believe to be solr schema conventions to have all the schema fields as lower-case.
> Thanks.
