Whilst upgrading a public web site that I had previously created in SharePoint 2007, during testing I noticed this strange number appearing at the end of my upgraded search results page. After the last result I was seeing a number like 68050. This number changed as I performed more searches.
I hadn't touched my custom search results XSLT at all during the upgrade, so I was wondering why this number started appearing. To troubleshoot, I first edited the search results page and changed the XSLT so that I could see the Search Results XML. The XSLT looked like:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
This revealed to me 2 new elements right before the end of the </all_results> tag. The extra elements were 'totalresults' and 'numberofresults'.
As SharePoint 2010 now uses Federated Search Locations with custom XSLT allocated to each location, I decided to look to see what the OOB 'Local Search Results' location was doing. Turns out that it now includes a couple of extra XSLT templates:
So I added these to extra XSLT templates into my custom XSLT and voila! No more strange number at the end of my search results.
