cts:Query from sem:SPARQL

How can I create a cts:query from sem:sparql…

Background, I am tyring create a custom constraint, and for that it needs to return cts:query.. but in my custom constraint I want to do sparql.. how do I do this.. eg:

sem:sparql("select DISTINCT ?subject  
            from 
           <http://rdf.abbvienet.com/entity/abbvie/biologic> 
           where {?subject <http://schemas.abbvienet.com/entity/target> <http://rdf.abbvienet.com/entity/ncbi/target/695>} ")

Solution

I think I figured out .. need to use cts:triple-range-query

If anyone is interested.. following is what I did for my eg sparq above..

  cts:and-query((cts:triple-range-query((), sem:iri('http://schemas.abbvienet.com/entity/target'), 
                                                              sem:iri('http://rdf.abbvienet.com/entity/ncbi/target/695')),
                                   cts:collection-query('http://rdf.abbvienet.com/entity/abbvie/biologic'))))

Please let me know if there is nicer way to do this :) ?
