My understanding was that searching for text using GREP should behave the same in InCopy as it does in InDesign.

In my experience it does not and I am wondering whether some module in InCopy has gone wonky.

Correct, it should. Try trashing your preferences (hold down ctrl-alt-shift while starting IC).

You saying that if you have a document with a single paragraph "hello", you cannot search for "hello" in the GREP tab of Find/Change?

You do have the scope of the search set to Document, rather than, say, Selection or To End of Story?

This is InCopy CS3, running on a central server using Citrix and Windows XP Server edition. Our IT department simply has no idea and as I am one of only 2-3 people of hundreds on the system using GREP, they are unwilling to assign resources to find out.

So any suggestions welcome.

That is going to limit diagnostics. No chance of installing on your own client machine, I take it.

What about my suggestion on reproducing with a simple and clean/new document?

Does anyone know if InDesign/Incopy share the same copy of the same plug-in(s) to allow GREP searching or do they each have their own copy. If latter, guessing the InCopy one(s) wonky. Anyone know what they're called. FYI: Once in a very long while a GREP text search works when I relaunch, but only the first time I run it. Thereafter, nope.

InCopy and InDesign are really the same program. They share almost all their code.

But maybe you're asking if they actually literally share the file, or have their own copy? They have each have their own copies, the shared stuff is only for stuff shared with other Adobe applications, like the PDF library or whatnot.

Which plugin? Not offhand. I would guess Text.InDesignPlugin (err, TEXT.RPLN, I guess, under Windows?).
