Try even simpler queries.
In fact try `select * where {?s ?p ?o} limit 10` just to make sure there's
something there. (If there's nothing then you need to be asking a different
question.)
If there is you can start adding constraints in, eg `[crm:E21_Person ?person]`,
making sure that works, etc.
Starting from something small and growing it works with queries just like
it works for code -- if you don't do it, then you end up with a big problem
object with overwhelming detail and no idea which bit might be the
broken one.
