[MarkLogic Dev General] cts.search v cts:search

You can xpath down the results in JavaScript.  In your case, you end up returning the whole document anyway I think because you are walking up the tree from //word.

This is not quite what you want to do, but it is similar (and requires a range index on concepts/@year)

var res = new Array();
for (var x of cts.search(cts.elementWordQuery(xs.QName("word"), 
                                  "tenant for life", ["exact"]),
                        cts.indexOrder(
                          cts.elementAttributeReference(
                            xs.QName("concepts"), xs.QName("year"))))) {
res.push(x.xpath(".//word"));
};
res;

Just guessing, but it might be pretty difficult to allow searchable expression arguments within a JavaScript evaluation environment. It might mean extending JavaScript syntax, or passing in the searchable expression as a string.

Speaking of strings, one workaround would be to do that bit in XQuery and call the XQuery from JavaScript. You could pass in a string that holds the searchable expression, and use that to build a cts:search expression, then call xdmp:value.

But if that sounds familiar, maybe it's because that's pretty much what search:resolve-nodes already does. You should be able to require() the search API module into your server-side JavaScript code and call it from there.
