Search Records Error : API call cannot be completed as the minimum field value length is not 2 in criteria value

Hi,

  https://crm.zoho.com/crm/private/xml/Leads/searchRecords?authtoken=someAuthToken&scope=crmapi&criteria=(Quote Number:1)

 gives

<response uri="/crm/private/xml/Leads/searchRecords">
      <error>
            <code>4832</code>
            <message>
                  API call cannot be completed as the minimum field value length is not 2 in criteria value
            </message>
      </error>
</response> .

I have got quote numbers less than 10. I need to search details for the quote numbers less than 10. Any value with less than 10 shows the same error.

Please advice how to solve this condition.

Thank you in advance
