The Jena list can't really answer questions about "any RDF store", but for TDB, you begin with basic covering indexes, so you do not need to add anything (in fact you cannot add anything) to provide more indexing for standard SPARQL forms.
As has been pointed out, there are _extensions_ to SPARQL provided by Jena that can make use of additional indexes: https://jena.apache.org/documentation/query/text-query.html and https://jena.apache.org/documentation/query/spatial-query.html --- A.
