When selecting records by Bulk APIs, how to make search string for the searched text containing single quote?

Hi all,

When trying to search some Contacts from Eloqua by Bulk APIs, I have to make a search string which would list out some specified EmailAddress.

Unfortunately, I meet several emails who have single quote in their spelling. I got 'The remote server returned an error: (500) Internal Server Error.' error when both using them directly and making single quote twice.

Any suggestions?

I am told that I could put the selected text into double quotes when it contains single quotes. But it works for SOAP APIs but not Bulk APIs.

Thanks,

Biao
