How can I exclude pages that have been redirected to other pages using "umbracoRedirect" from displaying in the xsltSearch results?

```
<xsl:variable name="possibleNodes" select="$items/descendant-or-self::*[
     @isDoc
     and string(umbracoNaviHide) != '1'
     and name() != 'ImageGalleryPhoto'
     and string(umbracoRedirect) != '1' <!-- How to hide umbracoRedirect from search ?? -->
     and count(attribute::id)=1
     and (umbraco.library:IsProtected(@id, @path) = false()
     or umbraco.library:HasAccess(@id, @path) = true())
]"/>

```
