Google Custom Engine - Specific dates

I would like to know how to make a custom Google search engine that only returns results between specific dates. Say 2000 to 2006.

When testing the below custom engine, it seems to work ok, but does not bring in results from the customized dates. Just recent results.

When using the engine for a search, "custom footprint" "allintitle:test", at the bottom of the tab is says "fetching proxies..." then it hangs.


[UserEngine]
Displayname=Custom Engine
QueryString=http://www.google.com/search?complete=0&output=ie&hl=en&q={KEYWORD}&num=100&start={PAGENUM}&tbs=cdr:1,cd_min:2000,cd_max:2006
MustBeInLink=http:
MustNotBeInLink=webcache.google|q=related:
JustBeforeLink=/url?q=
RightAfterLink=&sa=U&
PageStart=0
PageInc=100
NextPageMarker=Next
Translation=%3f=?|%3d==|%26=&|%3a=:|&=&|%2F=/
headerData=
SSLVersion=0
Favicon=
GracePeriod=0
UserAgent=
Selected=1
FollowRelocation=0
AddRelative=
AddFieldValue=
ClearCookies=0
ReadOnly=0

Any ideas?

Thanks
