I have 10 documents loaded in Mark Logic, each containing information about
a single book. Below is a sample document.

<?xml version="1.0" encoding="UTF-8"?>
<book xmlns:sb="http://www.sb.com/namespaces/sb";>
<title>The Life of David Gale</title>
<genre>fiction</genre>
<desc>....</desc>
<review>...</review>
</book>

I have defined string range index on the "genre" element so that I can facet
on genres when user search for books. I am trying to use the search:search
API in 4.1 but can't get this to work. The search works fine, but no facets
get returned. Here is the code from CQ:

xquery version "1.0-ml";
import module namespace search = "http://marklogic.com/appservices/search";
at "/MarkLogic/appservices/search/search.xqy";
search:search("life",
<options xmlns="http://marklogic.com/appservices/search";>
  <constraint name="facet-on-genre">
      <range type="xs:string" facet="true">
          <facet-option>limit=10</facet-option>
          <element ns="http://www.sb.com/namespaces/sb"; name="genre"/>
      </range>
  </constraint>
</options>)

Here is the response I get:

<search:response total="4" start="1" page-length="10"
xmlns:search="http://marklogic.com/appservices/search";>
  <search:result index="1" uri="a.xml" path="doc(&quot;a.xml&quot;)"
score="80" confidence="0.430638" fitness="0.67929">
    <search:snippet>...</search:snippet>
  </search:result>
  <search:result index="2" uri="c.xml" path="doc(&quot;c.xml&quot;)"
score="80" confidence="0.430638" fitness="0.67929">
    <search:snippet>...</search:snippet>
  </search:result>

  ...2 more search-result elements...

  <search:facet name="facet-on-genre"/>
  <search:qtext>refrigerator</search:qtext>
  <search:metrics>
    <search:query-resolution-time>PT0.016S</search:query-resolution-time>
    <search:facet-resolution-time>PT0S</search:facet-resolution-time>
    <search:snippet-resolution-time>PT0.016S</search:snippet-resolution-time>
    <search:total-time>PT0.032S</search:total-time>
  </search:metrics>
</search:response>


Can someone please help?

Thanks.
