I am seeing different relevancy scores for the same documents, between browser 
refreshes.  Any ideas why?  The query is the same, index is the same - why 
would score change?

Example:
First request returns:
<doc>
<str name="title">Stroke Anticoagulation and Prophylaxis</str>
<float name="score">3.463463</float>
</doc>
<doc>
<str name="title">Hemorrhagic Stroke</str>
<float name="score">3.463463</float>
</doc>
<doc>
<str name="title">Vertebrobasilar Stroke</str>
<float name="score">3.460521</float>
</doc>

Second request:
<doc>
<str name="title">Vertebrobasilar Stroke</str>
<float name="score">3.460521</float>
</doc>
<doc>
<str name="title">Hemorrhagic Stroke</str>
<float name="score">3.4484053</float>
</doc>
<doc>
<str name="title">Stroke Anticoagulation and Prophylaxis</str>
<float name="score">3.4484053</float>
</doc>

Third request:
<doc>
<str name="title">Stroke Anticoagulation and Prophylaxis</str>
<float name="score">3.463463</float>
</doc>
<doc>
<str name="title">Hemorrhagic Stroke</str>
<float name="score">3.463463</float>
</doc>
<doc>
<str name="title">Vertebrobasilar Stroke</str>
<float name="score">3.402718</float>
</doc>
