The server-side field index queries can only support operations on indexed fields. Additionally, queries that have differing ranges (i.e. one range at the fieldname level and another at the fieldValue level) are not currently supported. This class removes these conflicts from the query as well as sets proper capitalization configurations etc. Once the query has been modified, you can pass it to the BooleanLogicIterator on the server-side via the options map.
