Quite often you will need to customise the search results and ensure that your custom metadata mappings are displaying correctly.
To view the raw results, I undertake the following...
a) Edit the results page (results, or people depending on what you are looking to modify
b) Add a new core results web part (again people or results)
c) Add your columns, fixed queries etc
d) Click the Edit XSLT button and replace the XSLT with the following
<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" />
<xsl:template match="/">
<xmp><xsl:copy-of select="*"/></xmp>
</xsl:template>
</xsl:stylesheet>
Save everything and you can now see the raw results.
