Kim Taylor commented on SOLR-752:
---------------------------------

I've had a look into this. Simon is right, DefaultSolrHighlighter uses doc.getValues(fieldName) to retrieve the field. lucene.document.Document.getValues() calls stringValue on the appropriate field. The problem is that when FieldsWriter/Reader read fields from segments, the supplied CompressedField gets converted into a Field, which does not know how to interpret fieldsData. I've added another patch that alters DefaultSolrHighlighter to use the schema FieldType (in this case CompressedField) to properly interpred fieldsData.

> It would be good if Solr handled field compression outside of Lucene's Field.COMPRESS capabilities, since those capabilities are less than ideal when it comes to control over compression.
