I have Search Server Express 2010 that is crawling web site content such as this:
<meta name="publishDate" content="04/26/2011 16:58:00" />
In search administration my tags appear in Crawled Properties as a text field:
I want to map publishDate to the lastModifiedDate property, but I can't. How can I change its type to 'date'?
Tried to do it with powershell and command Set-SPEnterpriseSearchMetadataCrawledProperty but had no luck. It says the VariantType parameter doesn't exist.
