Search API error: 4832: Invalid parameter value

My search API doesn't work.

I used this to search my Accounts table:
https://crm.zoho.com/crm/private/xml/Accounts/getSearchRecords?authtoken=xxxxx&scope=crmapi&newFormat=1&selectColumns=All&searchCondition=(ACCOUNTID|=|123456)

I got this error:
4832: Invalid parameter value
