issue with indexing customised attributes

nikhil_palav

I am using TS6.7.1.I am using Advanced Search for searching customized attributes.I am not able to search the customised attributes.I have included them in FieldMapping.xml but not in search_custom.xml.so i have all the attributes listed in the dropdown of Advanced Search UI alongwith the default one's.But when i try to search through the content based on that attribute i am not able to search them.
I am attaching my FieldMapping.xml herewith.after making the entry i stop & start the Index and Search services respectively.so that the entry is populated in the drop down of Advanced Search UI.Then i purge the branch(iwndxpurgebr /default/main/) & again add it to indexing(iwndxaddbr /default/main/) so that the customised attribute is indexed.But when i run iwsrchattrib -t it does not give me the list of attributes indexed.path is from Y:/ onwards to templatedata/category-name/data-type .on iwsrchattrib -e it does give me the default list of attributes indexed alongwith my customized one's which are listed in the dropdown.
I am not able to identify whether i am able to index my customized attributes or not.
The similar thing happened when i tried to index the fields in a DCT.
Please let me know how i should go about it.
Thanks in advance.
