This is really close to what I need. Now I just need to constrain the results to only be for documents that have "image" for the root element. I tried adding this to the search options:
<additional-query>/image</additional-query> but it didn't affect the results. I suppose because the "image" elements are already being retrieved by the searchable expression, adding any additional-query with do nothing, since everything is already satisfied in the properties query. So how I can I just return the image documents, and sort them by last-modified?

If you search over the properties you can get this to work. I cannot immediately think of how you can do this using the search API without searching over the properties. Here is how to do it by searching over the properties (you need a dateTime range index on prop:last-modified for this to be optimized): xquery version "1.0-ml"; import module namespace search = "http://marklogic.com/appservices/search"; at "/MarkLogic/appservices/search/search.xqy"; declare namespace prop="http://marklogic.com/xdmp/property";; let $options := <options xmlns="http://marklogic.com/appservices/search";> <searchable-expression>xdmp:document-properties() </searchable-expression> <debug>true</debug> <term> <empty apply="all-results" /> </term> <sort-order type="xs:dateTime" direction="descending"> <element ns="http://marklogic.com/xdmp/property"; name="last-modified"/> </sort-order> </options> return search:search("", $options) -Danny From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, August 18, 2010 1:02 PM To: [email protected] Subject: [MarkLogic Dev General] How to query all docs and sort by last-modified property? I have xml files in the database with the root element of “image”. What I want to do is to use search:search to query all the image elements (no search term) and order them by the last-modified property. Below is what I have tried, but it doesn’t seem to actually be sorting on the last-modified property (I do already have an element range index on the property). It just returns hits based on relevance which is meaningless in this type of query. Does anyone know how I can get this to work? xquery version '1.0-ml'; import module namespace search = "http://marklogic.com/appservices/search"; at "/MarkLogic/appservices/search/search.xqy"; let $options := <options xmlns="http://marklogic.com/appservices/search";> <searchable-expression xmlns="http://marklogic.com/appservices/search";>/image</searchable-expression> <search:sort-order type="xs:dateTime" direction="descending"> <search:element ns="http://marklogic.com/xdmp/property"; name="last-modified"/> </search:sort-order> </options> return search:search("", $options, 1, 16) _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
