Thanks David for your help. I’ve got my search working. :)

That works, but still selects the adobe in blah@adobe.com

I’m using STEP’n’Design, the plug-in which links STEP by Stibo Systems to Indesign.

It’s a shame you can’t control whether you are using typographer’s quotes or not using a stylesheet checkbox. Same goes for the Change Case options.

Anyway, I fixed my problem by reimporting the data on a different machine with Typographer’s Quotes turned off. I don’t know why it didn’t work on my machine, but there you go.
