Sphinx and wordforms

Question

How could I make Sphinx to recognize "auto" and "car" as similar words?

Let's image I have three database records

Andy likes to drive auto.
Mary don't like to drive car.
Bob is going to buy automobile.

Here is sample queries and it's results...

query: car
result: Mary don't like to drive car.
-------------------------------------
query: auto
result: Andy likes to drive auto.
-------------------------------------
query: automobile
Bob is going to buy automobile.

..but I want sphinx to return...

query: car
result:
Andy likes to drive auto.
Mary don't like to drive car.
Bob is going to buy automobile.
-------------------------------------
query: auto
result:
Andy likes to drive auto.
Mary don't like to drive car.
Bob is going to buy automobile.
-------------------------------------
query: automobile
result:
Andy likes to drive auto.
Mary don't like to drive car.
Bob is going to buy automobile.

I know that Sphinx have stowords, but what should I put into stopwords dictionary to make Sphinx think this way?

Thank you.

all you have to do is supply sphinx with a correctly-formatted text file of wordforms in your .conf file.
