We have developed a SharePoint search connector that allows us to crawl and index an external content source.
It is based on the framework http://msdn.microsoft.com/en-us/library/ee556429.aspx
Some of the fields crawled contain multiple values e.g. comma separated. SharePoint does not see these fields as multi valued.
We have created a managed property that maps to the crawled field and set it to "Has multiple values", but this does not appear to be working
Does anyone know how to have data crawled using the SharePoint Server search connector framework appear as a multi valued?
Thanks omlin for the tip.
The correct separator is ;#
Switching to use this in the data we are returning to SharePoint has enabled it to pick up the value as multi valued
