Information Steward : Custom Content type

Hello,

We are trying to set up Data cleansing strategy similar to the one mentioned in the below link :

http://scn.sap.com/community/information-steward/blog/2013/12/31/determining-duplicates-and-a-matching-strategy

We donot want to use the Standard content type available in Information Steward.

Hence we have created a Custom Content type called 'Text' from the Option :

For a the particular field for which we want to do the profiling

     - Select 'Associate content type'

     - Select 'New'

     - Save

     - Select this new content type for associating the field with the content type.

Utp this step, we are able to map this newly defined content type to the Field.

However, we are not sure how to configure the logic for this newly defined Content type.

Any inputs or examples on the usage of Custom Content type would be apprciated

Thanks & Regards,

Krupali
