Mapping with % doesn't work as expected.

Mar 23, 2009 at 1:12 PM
I have configured my fileExtension column with mappings like doc%, ppt%, xls%, it shows me the result like:

ASPX (125)
Word (106)
PDF (10)
HTM (6)
Word (2)

As you can see, I get the Word search result twice with different search result numbers [106 and 2], 106 is for the .doc documents and 2 is for .docx documents. My question is why the wildcard delimeter % is not combining both the results related to word here? ie. showing one result for .DOC and .DOCX document under Word with 108 results? shouldn't Mapping with % be working like this or I am misunderstanding the concept of wildcard mapping?
