I have a webscript that's using seach.query:

var def =
   {
      query: "*//.[@wca:parentformname='formname']",
      store: "avm://" + args.storeid,
      language: "jcr-xpath"
   };
   var results = search.query(def);‍‍‍‍‍‍‍

And when I run it, I get this error:

Exception:   org.alfresco.repo.search.SearcherException - Unknown query language: jcr-xpath

I am using Enterprise - v3.2.0 (304).   Why isn't this working.  The query works in the node browser when I select "selectnodes" as the language.  How do I enable jcr-xpath so that I can query for attributes?

Hello,

I have the same issue using Alfresco Community v3.3.0 (g 2860).

That is what I'm trying inside a web script:

// xpath query example
var searchStr3 = {
   query: "//*[@cm:name='sample-file-a.txt']",
   language: "jcr-xpath"
}
var xpathSearchNodes = search.query(searchStr3);
logger.log("xpath query found " + xpathSearchNodes.length + " node(s)");
model.xpathResult = xpathSearchNodes;
‍‍‍‍‍‍‍‍‍‍

That's the stack trace I get:

Is this a bug?

The feature is working in principle via Node Browser. Furthermore its described in the Wiki (http://wiki.alfresco.com/wiki/Search_Documentation#XPath_search_using_the_node_service).
