Sitecore Analytics Robots Exclusion
===

We are using Sitecore CMS 6.5.0 and DMS 2.0.1 rev.120427. We are using CoveoEnterpriseSearch in our application. The problem is whenever there is a visit to a page, 3 unnecessary rows are inserting in analytics databse (pages table with url '/Coveo/Anonymous/').

Settings in `Sitecore.Analytics`.Config related to robots are,

     <setting name="Analytics.AutoDetectBots" value="true" />
     <setting name="Analytics.Robots.IgnoreRobots" value="true" />
     <setting name="Analytics.Robots.IgnoreAutoRobots" value="true" />

How could I stop inserting of those records? We've tried placing user agent 'Coveo Sitecore Crawler' under `<excludedUserAgents>` tag in Sitecore.Analytics.ExcludeRobots.Config. And we created a 'robots.txt' file in the root with Coveo user-agent & Disallow options with no use.

Any suggestions?
Thanks in advance.
