Can you use getSearchRecords to get ids greater then?

https://crm.zoho.com/crm/private/xml/Leads/getSearchRecords? authtoken= Auth Token &scope= crmapi &newFormat=1&selectColumns=All&searchCondition=(LEADID|>|12346789)

Should this work?
I'm getting this response:

{"response": {"uri":"/crm/private/json/Leads/getSearchRecords","error": {"code":4832,"message":"Invalid parameter value"}}}
