Getting Best Bet data from synonym

[Amit]

Hi,

I am writing a custom webpart for fetching best bets data using MOSS API.
I have been able to find the best bets links using keywords.
Used
Keyword.AllKeyWords[<Keyword term>] for fetching this.
But till now i have not been able to find the Best Bets data using synonums
entered against a keyword.
i.e. while configuring Search Keywords i entered a keyword,3 synonyms
against this keyword and couple of best bets.

Now in my custom code when i search with this keyword i am able to get the
configured best bets,but when i search using synonym configured against
keyword it is not retrieving best bets for it.

This is happening perfectly in OOB webpart.
Any pointers on how to achieve this?

Regards,
Amit
