   1. ''recommended but not necessary''
-  1. 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

speedup may be possible. Note, that you must index the field in order to be able to use termVectors,
termOffset and termPositions.
