SOLR newbie question: How to filter the results based on my Unique Key

[Venu Mittal]

Hi List,

Is it possible to filter out the duplicate results using a particular field in 
the document.
e.g.

<doc>
 <field name="cust_id>123</field>
 <field name="unique_id>1</field>   
<field name="email>a...@b.com</field>
</doc>
<doc>
 <field name="cust_id>123</field>
 <field name="unique_id>2</field>
<field name="email>a...@b.com</field>
</doc>

Now if I search for email = a...@b.com I get 2 search results but I want to 
send just one record cause my cust_id is same. Is it possible or do I need to 
handle it in the calling application.
 
Thanks
