So, I want to count the number of skos:Concept records that have a skos:broader child.
I have fragmented on skos:Concept (there are 352950 skos:Concept fragments in the DB). The following query works as expected: declare namespace skos="http://www.w3.org/2004/02/skos/core#";; xdmp:estimate(//skos:Concept[skos:broader]) This returns 352944 (which is correct) However, xdmp:estimate(//skos:Concept[not(skos:broader)]) returns 352950 (every skos:Concept fragment in the DB instead of the expected value of 6). So, I then moved on to search. xdmp:estimate(cts:search(//skos:Concept, cts:not-query(cts:element-query((QName("http://www.w3.org/2004/02/skos/core#","broader";)), cts:and-query(()))))) returns a value of 6. and xdmp:estimate(cts:search(//skos:Concept, cts:element-query((QName("http://www.w3.org/2004/02/skos/core#","broader";)), cts:and-query(())))) returns a value of 352944. So, since MarkLogic indexes parent-child relationships, why wouldn't the first simple query ... just using xpath expressions ... return the correct result. Thanks. Darin. p.s. No, I didn't bother to do a trace or xdmp:plan ;-) The xpath example appears so simple (on the surface) I'm a bit stumped as to why this would not correctly return an unfiltered result. _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
