I don't think you can rename it in the index. However, you may be able to rename it during the query: https://lucene.apache.org/solr/guide/6_6/common-query-parameters.html#CommonQueryParameters-FieldNameAliases
Or, if you use eDisMax, during query rewriting: https://lucene.apache.org/solr/guide/6_6/the-extended-dismax-query-parser.html , see example at: https://github.com/arafalov/solr-indexing-book/blob/master/published/languages/conf/solrconfig.xml#L20-L21 These two may need to play together actually, if you want it to be fully transparent to the client code. See the #37 of the example above. Regards, Alex.
