WordBreak spell correction makes split terms optional?

[Carrie Coy]

The user query  "design your ownbinoculars"  is corrected by the 
'wordbreak' dictionary to:

<str name="querystring">design your (own binoculars)</str>
Where are the parentheses coming from?  Can I strip them with a 
post-processing filter?   The parentheses make the terms optional, so, 
while the first match is excellent, the rest are irrelevant.

Thx,
Carrie Coy
