Hi

I want to use Synonym Token Filter,I need clarification before using  
analyzer:

a.) Suppose i have declare Synonym like\* _ipod, i-pod,_ i pod _then it's  
necessary to index both data(ipod, i-pod, i pod).  
b.) if index contain repeated data like ipod, i-pod,_ i pod mobile,\*ipod TV,i  
-pod computer,_ipod, i-pod, i pod_ \* \*and Synonym declare as ipod, i-pod,\*i pod  
\*can it's work and what the aspect ed result i got.

Thank
