<ul>
<li>I told him we never finished it, and that he should try to use the <code>/items/find-by-metadata-field</code> endpoint, with the caveat that you need to match the language attribute exactly (ie &ldquo;en&rdquo;, &ldquo;en_US&rdquo;, null, etc)</li>
<li>I asked him how many terms they are interested in, as we could probably make it easier by normalizing the language attributes of these fields (it would help us anyways)</li>
<li>He says he&rsquo;s getting HTTP 401 errors when trying to search for CPWF subject terms, which I can reproduce:</li>
</ul></li>

<ul>
<li>Note that curl only shows the HTTP 401 error if you use <code>-f</code> (fail), and only then if you <em>don&rsquo;t</em> include <code>-s</code>
<ul>
<li>I see there are about 1,000 items using CPWF subject &ldquo;WATER MANAGEMENT&rdquo; in the database, so there should definitely be results</li>
<li>The breakdown of <code>text_lang</code> fields used in those items is 942:</li>
