    <title>topic Displaying 'Unknown' when Lookup fail to find a match in Splunk Search</title>
    <link>https://community.splunk.com/t5/Splunk-Search/Displaying-Unknown-when-Lookup-fail-to-find-a-match/m-p/107536#M27946</link>
    <description>&lt;P&gt;I have an Automatic Lookup working just fine.&lt;BR /&gt;
Some of the values Im matching doesn't exist yet on the CSV table (they are populated once a day).&lt;BR /&gt;
Is there any way to display UNKNOWN as a value for the field when the lookup doesnt exist on the table?&lt;BR /&gt;
For example, if my csv lookup table looks like:&lt;BR /&gt;
Name -- SSN&lt;/P&gt;

&lt;P&gt;And Sometimes I dont have the Name for a SSN until the next day, so I need to mark the field as 'Unknown' when the search returns a SSN that I dont have match for the name yet.&lt;/P&gt;

&lt;P&gt;Thanks!&lt;/P&gt;</description>

      <description>&lt;P&gt;Manager &amp;gt;&amp;gt; Lookups &amp;gt;&amp;gt; Lookup Definition &amp;gt;&amp;gt; &lt;YOURLOOKUPTABLE&gt;&lt;/YOURLOOKUPTABLE&gt;&lt;/P&gt;

&lt;P&gt;check the advanced options checkbox&lt;/P&gt;

&lt;P&gt;In the Minimum matches text box add:&lt;BR /&gt;
1&lt;/P&gt;

&lt;P&gt;In the Default matches text box add:&lt;BR /&gt;
UNKNOWN &lt;/P&gt;

&lt;P&gt;then save&lt;/P&gt;</description>
