Notes:
- recommended but not necessary
- stored must always be true for highlighting. If you also add both termVectors and termOffsets, this can be used to boost performance. (Without termVectors/termOffsets, Solr needs to reanalyze the whole field to perform highlighting.) If you furthermore add termPositions, additional speedup may be possible. Note, that you must index the field in order to be able to use termVectors, termOffsets and termPositions.
- a tokenizer must be defined for the field, but it doesn't need to be indexed
- For use with the TermVectorComponent
- Uses the term vector if present, otherwise the stored field. Reanalyzes the document if using the stored field.
For further considerations for faceting, see also SolrFacetingOverview. For more information on term frequency, positions, offsets etc. see TermVectorComponent.
