There is no tooltip on search result page on view count field if a question has more than 1000 views. That view count field is located just below of vote and answer count fields on the left.
See for example https://stackoverflow.com/questions/tagged?tagnames=java&sort=votes&pagesize=50 and its first question which has following html code:
<div class="views hot">31k views</div>
In most places this kind of inaccurate values have tooltips which show the actual accurate value. Thus, the above fragment should have
title="31,157 views" attribute.
If there is less than 1000 views, the search result page shows to accurate view count and no tooltip is needed.
