<li>Also, Solr&rsquo;s <code>fq</code> is similar to the regular <code>q</code> query parameter, but it is considered for the Solr query cache so it should be faster for multiple queries</li>
</ul>
<h2 id="2018-09-18">2018-09-18</h2>
<ul>
<li>I managed to create a simple proof of concept REST API to expose item view and download statistics: <a href="https://github.com/alanorth/cgspace-statistics-api">cgspace-statistics-api</a></li>
<li>It uses the Python-based <a href="https://falcon.readthedocs.io">Falcon</a> web framework and talks to Solr directly using the <a href="https://github.com/moonlitesolutions/SolrClient">SolrClient</a> library (which seems to have issues in Python 3.7 currently)</li>
<li>After deploying on DSpace Test I can then get the stats for an item using its ID:</li>
</ul>
<pre><code>$ http -b 'https://dspacetest.cgiar.org/rest/statistics/item?id=110988'
{
&quot;downloads&quot;: 2,
&quot;id&quot;: 110988,
&quot;views&quot;: 15
}
</code></pre>
<ul>
<li>The numbers are different than those that come from Atmire&rsquo;s statlets for some reason, but as I&rsquo;m querying Solr directly, I have no idea where their numbers come from!</li>
<li>Moayad from CodeObia asked if I could make the API be able to paginate over all items, for example: /statistics?limit=100&amp;page=1</li>
<li>Getting all the item IDs from PostgreSQL is certainly easy:</li>
</ul>
<pre><code>dspace=# select item_id from item where in_archive is True and withdrawn is False and discoverable is True;
</code></pre>
<ul>
<li>The rest of the Falcon tooling will be more difficult&hellip;</li>
</ul>
