    copied!<p>I am new to Solr. I need to be able to search on image meta data in Solr. Also, I need to have the simple search and view ability to view the image in Solr.</p> <p>Currently, 1) I crawl the sites with apache Nutch and then run indexsolr command to send the data to Solr. 2) I added there </p> <pre><code>&lt;requestHandler name="/update/extract" class="solr.extraction.ExtractingRequestHandler" &gt; &lt;lst name="defaults"&gt; &lt;str name="fmap.content"&gt;text&lt;/str&gt; &lt;str name="lowernames"&gt;true&lt;/str&gt; &lt;str name="uprefix"&gt;attr_&lt;/str&gt; &lt;str name="captureAttr"&gt;true&lt;/str&gt; </code></pre> <p> </p> <p>and </p> <pre><code>&lt;lib dir="/path-to-solr/example/solr/collection1/extract" regex=".*\.jar" /&gt; </code></pre> <p>(I created a folder extract and move all the jars from solar dist folder in there as well as tika related jars) to solrconfig.xml</p> <p>3) added to schema.xml the following fields</p> <pre><code>&lt;field name="host" type="string" stored="false" indexed="true"/&gt; &lt;field name="segment" type="string" stored="true" indexed="false"/&gt; &lt;field name="digest" type="string" stored="true" indexed="false"/&gt; enter code here &lt;field name="boost" type="float" stored="true" indexed="false"/&gt; &lt;field name="tstamp" type="date" stored="true" indexed="false"/&gt; &lt;!-- fields for index-anchor plugin --&gt; &lt;field name="anchor" type="string" stored="true" indexed="true" multiValued="true"/&gt; &lt;!-- fields for index-more plugin --&gt; &lt;field name="type" type="string" stored="true" indexed="true" multiValued="true"/&gt; &lt;field name="contentLength" type="long" stored="true" indexed="false"/&gt; &lt;field name="lastModified" type="date" stored="true" indexed="false"/&gt; &lt;field name="date" type="date" stored="true" indexed="true"/&gt; &lt;field name="aperture" type="double" indexed="true" stored="true"/&gt; &lt;field name="exposure" type="string" indexed="true" stored="true"/&gt; &lt;field name="exposure_time" type="double" indexed="true" stored="true"/&gt; &lt;field name="focal" type="string" indexed="true" stored="true"/&gt; &lt;field name="focal_35" type="string" indexed="true" stored="true"/&gt; &lt;!-- for indexing and parsing metadata plugin --&gt; &lt;field name="metatag.description" type="string" stored="true" indexed="true"/&gt; &lt;field name="metatag.keywords" type="string" stored="true" indexed="true"/&gt; </code></pre> <p>Looks like I am still missing something, since I cannot see the images in Solr.</p> <p>Do I need to explicitly add each image via something like:</p> <pre><code>curl "http://127.0.0.1:8983/solr/update/extract?literal.id=n1&amp;commit=true" -F "myfile=@my_image.jpg" </code></pre> <p>? Thanks</p>
