i need some better way to search addressbook by number from my application

[Michal Seliga]

at the moment i use this code to search addressbook for contact by phone number 

callback:
static Boolean LookupCallback(void* ref)
{
    return false;
}

AddrCallerIDParamsType params;
SysNotifyParamType notify;

MemSet(&notify,sizeof(SysNotifyParamType),0);
MemSet(&params,sizeof(AddrCallerIDParamsType),0);
notify.notifyType=addrAppNotificationCmdCallerID;
notify.notifyDetailsP=&params;
params.lookupString="some phone number";
params.callback=LookupCallback;
CallWithCommand(sysFileTApplication,kPalmOneCreatorIDContacts,sysAppLaunchCm
if(params.uniqueID)
{
//found
}
else
{
//notfound
}

problem is that with this code contact is found only if i have it only once 
(when result is unique). for example if i have contact both in SIM addressbook 
and in real addresbook it will return that it didn't found anything

for what i need it would be good if i could persuade address aplication to 
return uid of first contact which matches and doesn't care about how many of 
them would match

i am sure its possible..but how?

all this is tested on treo650 so i need something what works there
