    <p>I receive strange problem with using fq param in requests to Solr</p> <pre><code>curl '127.0.0.1:8080/solr/app/select?rows=0&amp;start=0&amp;q=app+AND+categoryId:20' &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;response&gt; &lt;lst name="responseHeader"&gt;&lt;int name="status"&gt;0&lt;/int&gt;&lt;int name="QTime"&gt;1&lt;/int&gt; &lt;lst name="params"&gt;&lt;str name="start"&gt;0&lt;/str&gt;&lt;str name="q"&gt;app AND categoryId:20&lt;/str&gt; &lt;str name="rows"&gt;0&lt;/str&gt;&lt;/lst&gt;&lt;/lst&gt; &lt;result name="response" numFound="42236" start="0"&gt;&lt;/result&gt; &lt;/response&gt; </code></pre> <p>and second request</p> <pre><code>curl '127.0.0.1:8080/solr/app/select?rows=0&amp;start=0&amp;q=app+AND+categoryId:20&amp;fq=categoryId:20' &lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;response&gt; &lt;lst name="responseHeader"&gt;&lt;int name="status"&gt;0&lt;/int&gt;&lt;int name="QTime"&gt;1&lt;/int&gt; &lt;lst name="params"&gt;&lt;str name="start"&gt;0&lt;/str&gt;&lt;str name="q"&gt;app AND categoryId:20&lt;/str&gt; &lt;str name="fq"&gt;categoryId:20&lt;/str&gt;&lt;str name="rows"&gt;0&lt;/str&gt;&lt;/lst&gt;&lt;/lst&gt; &lt;result name="response" numFound="69480" start="0"&gt;&lt;/result&gt; &lt;/response&gt; </code></pre> <p>Different just in using addition param &amp;fq=categoryId:20 , but as you can see this filter also present in main query and must have no affect on result.</p> <p>I checked response and found a lot of duplicates in first request. </p> <p>also tags show 42236 docs for categoryId=20, </p> <p>So why query with &amp;fq=categoryId:20 return so lot(and duplicates) docs ? P.S. all other categories works correct.</p> <p>part of scheme:</p> <pre><code> &lt;field name="id" type="int" indexed="true" stored="true" required="true"/&gt; &lt;field name="title" type="text_general" indexed="true" stored="true" required="true"/&gt; &lt;field name="description" type="text_general" indexed="true" stored="false" required="true"/&gt; &lt;field name="categoryId" type="int" indexed="true" stored="false" required="true" multiValued="true"/&gt; &lt;field name="tags" type="string" indexed="true" stored="false" required="false" multiValued="true"/&gt; &lt;field name="type" type="int" indexed="true" stored="false" required="true"/&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
