ok, i try to get this list with SearchEngine.

Hello Jianchun,  We always recommend developers use try/catch when writing code, and you can elevate your developer experience by adding the logging helper-method to produce logs that are easier to navigate through. Example usage: #setLanguageLevel 4; #include "lib-log"; //This is the log-helper-method-library, but you can include this in your code directly if you want String mainMethod(){ return "foo"; } try { String bar = mainMethod(); } catch { printLine("Exception caught: " + error); printLine("...at " + errorLocation); log(406, 5, "Exception caught: " + error, "...at " + errorLocation); // Uses the logger-method from the include } The try/catch will mean your code will no longer crash, and you can catch the error and/or even implement notifications.  I also recommend you look at the option to activate trace on your script, but check the box "Only save if there is an unhandled exception" and use `forceSaveTrace(true)` in your catch-block. Have a SUPER day! //Eivind

Hi Thomas, try logging into the community page for bugs and wishes and then try checking the bug shared previously by Bas.  

Hi John, Could you provide us more information in this matter? When mentioning Case, do you mean a Request? Generally a customer is automatically added to the request through an incoming e-mail based on the From: address. And when sending an e-mail to the customer with To:, the customer would already be connected with the request.

Hi Eivind, i don't know the Version. We are using the online3.superoffice.com website.. I need to use the € in my code, to check a passsword. Wenn you debug your code, at line 4, you must have the 0x20AC, can you check it ? I use #setLanguageLevel 3; and you 4, that can be the difference ? Thanks Fabrice

Hi,  In 10.3.1 the email search was optimized, see Improve recipients search performance , possibly this was also fixed, you could try by upgrading to 10.3.3.? 

Hi Fabrice, Generally speaking, if a script is taking too long to complete then it's probably because the script is trying to do much more than what the CRMScript engine was designed for. CRMScript best practices | SuperOffice Docs There is too little information in the OP to better understand what task(s) the script is written to complete, but unless there is something wrong - like highly unoptimized code, then this is generally an indicator that the intended work would be best written as a custom application that leverages webhooks, etc. Best regards.
