            <title>[MODFQMMGR-45] Query builder - Slow performance of test queries executed against Items entity type</title>
                <link>https://folio-org.atlassian.net/browse/MODFQMMGR-45</link>
                <project id="10031" key="MODFQMMGR">mod-fqm-manager</project>
                    <description>&lt;p&gt;&lt;b&gt;Purpose/Overview:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Purpose of this story is to fix slow performance of queries executed against &quot;Items&quot; entity type.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Examples of slow queries:&lt;/b&gt;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Instance title = Ireland and the Irish:Cathleen ni Houlihan is alive and well. &amp;#8211; Takes 7 minutes to execute&lt;/li&gt;
	&lt;li&gt;Instance title Starts with Ireland &amp;#8211; Takes 7 minutes to execute&lt;/li&gt;
	&lt;li&gt;instance ID = 0918f889-26bc-4416-bece-9d076e11bdef &#160;-- this is much faster than the previous 2&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Proposed solution:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Create a smaller view that just join &quot;item&quot;, &quot;holdingrecords&quot; and &quot;instance&quot; tables.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

Note: because we convert text fields to lower case when doing text operators, we can&apos;t take full advantage of the indexes involved yet, but that will requite some extra work that is out of scope of this ticket&lt;/p&gt;</comment>
