Your problem is that the default handler for ExtractingRequestHandler, defined in solrconfig.xml, puts all Tika unidentified selected fields in fields named "ingored_XXXXX".

To solve this problem, you can simply add the field name "ignored_ *" to your Solr configuration as follows:

 <dynamicField name="ignored_*" type="ignored"/>

Remember to add an ignored type as well if you remove it from the default configuration:

 <fieldtype name="ignored" stored="false" indexed="false" multiValued="true" class="solr.StrField" />

This will stop your Solr from crashing if the Tika index fields that Solr is not aware of.
