Trouble getting the crawled properties to be any type but string
AOTX San Antonio
Hi,
We are in the process of implementing MOSS 2007 search, but we are having
trouble getting the crawled properties to be any type but string. There are
some html meta tags we are crawling who's content property should be
interpreted as a numeric, boolean, or datetime type value. How do you
configure the indexer to recognize this?
We were able to make this happen under SPPS 2003, by using the HTMLPROP SDK
sample. Can this still be used?
Thanks.

As for the MOSS search, all the properties search engine crawled from the
source documents are called "crawled properties" and they are generally
some string based values. And the MOSS 2007 search has a managed properties
setting which maintain a table of mapping between these "crawled
properties" and the "managed properties" that will be used for query. You
can find it in the shared service provider's search setting:
"Shared Services Administration: SharedServices1 > Search Settings >
Managed Properties"

Also, here are some other web articles discussing on the manged properties
mapping:

Did you try your suggestion of mapping a text crawled property to non-text
managed property? It did not work for me. When I attempt to do this I
receive the error message, "The settings could not be saved because of an
internal error: The variant type 31 cannot be mapped to managed data type
DateTime." This occurs when I attempt to map a text crawled property to a
new date time managed property.
How do you make a crawled property become a data type other than text? It
appears as though MOSS only lets you map similar data types, which makes
sense because implicit data conversion can be difficult and open to
interpretation.
