Hi, 

thank you for match information about zoho api.

today , i want to get invoice data of last month.

so i create a php code below using zoho-php-sdk v2.

2. $zcrmModuleIns = \ZCRMModule::getInstance("Invoices");
   
3. $from = '2019/07/31';
   
4. $to = '2019/09/01';
   
5. $criteria = '((Invoice_Date:After:'.$from.') and (Invoice_Date:Before:'.$to.'))';
6. $response = $zcrmModuleIns->searchRecordsByCriteria($criteria);

but i get only error message like this.

ZCRMException invalid query formed Request

i want to know how i can get data.

2. // this goes well
3. $zcrmModuleIns = \ZCRMModule::getInstance("Leads");
   
4. $criteria = '((Last_Name:equals:Example) or (Email:starts_with:example@example.com))';
5. 
   
6. //this goes well
