Hi Gary, Are you aware that cts:element-value-match is returning values that match the pattern, not a query that does so? Run it separately. Wouldn't be surprised if it would return an empty sequence, you might want to try '*' instead of '?' as pattern..
Cts:and-query doesn't return doc-id's. Queries are always fragment-based, and result in a positive match if the query (and its sub-queries) are satisfied within a single fragment, with the exception of document-fragment-query.. Kind regards, Geert Van: [email protected] [mailto:[email protected]] Namens Gary Larsen Verzonden: dinsdag 21 juni 2011 20:16 Aan: 'General MarkLogic Developer Discussion' Onderwerp: Re: [MarkLogic Dev General] element values in fragments Hi Mike, Using cts:uris() and cts:document-query() I was able to get cts:element-values() to return values. It would help me to understand why a cts:and-query() does not work in this case. I was under the assumption that a cts:and-query() would return doc ids which would be equivalent.

Alternatively, you could use cts:uris() to get all the document uris that match the top-level part of the query, then feed those uris into a cts:document-query() that tests the sub-fragments. -- Mike On 21 Jun 2011, at 10:05 , Gary Larsen wrote: > Hi Danny, > > The original $cq was finding results, but removing the > document-fragment-query still returns an empty sequence.
