SOLR Undefined Field Length

Using SOLR and the DataImportHandler, we have indexed our database. The database has a field that contains concatenated property data for the row. We use a transformer in our data-config.xml file to read that field and split it into several dynamic fields.

We use this data to search against as facets.

We can search some of the fields as facets and it works perfectly, however, some of the fields cannot do a facet search (e.g. fq=attr_fieldname:"facetval"). When searching, they return "HTTP Status 400 - undefined field Type" or "HTTP Status 400 - undefined field Length"

We can see the dynamic fields are created when viewing the schema browser, s开发者_StackOverflowo there isn't a question on whether or not the field name is correct.

In our schema.xml, the dynamic field is defined as a string type that does not allow multivalued.

Any ideas about what is causing this, or what we can do to prevent it?

Thanks!

UPDATE--- Here is the dynamic field definition that we're using:

  <dynamicField name="attr_*" type="string" indexed="true" stored="false" multiValued="false"/>

UPDATE 2--- Is anyone aware of an issue caused by a dynamic field that would end up being named "attr_type" or "attr_length"? Based on one of the comments, it was suggested that maybe we were sending "length" or "type" as a field name. We aren't doing that, but we are sending "attr_length" or "attr_type"
