Probably both need to be done. Currently terms like "Des Plaines Division Headquarters" and "DES PLAINES DIVISION HEADQUARTERS" are treated as separate terms, when in reality they are the same.
Cleaning of the data (standardizing names, locations, dates, etc.) should be done. and possibly adjustments to how Solr (?) interprets lower and upper case terms/names.
