Hi, I'm by no means expert on this so if anyone sees a mistake please correct me.
I think you need to index this field, since boost functions are added to the query as optional clauses (https://lucene.apache.org/solr/guide/6_6/the-dismax-query-parser.html#TheDisMaxQueryParser-Thebf_BoostFunctions_Parameter). It's like boosting a regular field by putting ^2 next to it in a query. Storing or enabling docValues will unnecesarily consume space/memory.
