Hi Geert, Properties are indexed, and you can search on properties by putting the document properties in the first argument of cts:search. For example, the following:
cts:search(xdmp:document-properties(), "hello") will return all of the properties that have "hello" in them. You can also use the properties:: axis in XPath to switch to the document properties (in a predicate, for example). Joins between the document and its corresponding properties document are fast for simple types in the properties. Both fragments still need to be fetched, which is what Mike was getting at I think, but for many applications properties work extremely well. CPF, for example, stores its metadata in properties. See chapter 14 in the Developer's Guide (p112) for more information on properties. -Danny -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Geert Josten Sent: Monday, March 16, 2009 11:18 AM To: General Mark Logic Developer Discussion Subject: RE: [MarkLogic Dev General] Searching on document properties?
