If I have a variable set up that is linked to custom property in my part, can I search for it even if it is not on the data card? It's no problem to add it to the card; it's just more of a general question. I assumed it was possible, but I can't seem to do it.
You can setup indexing on the server then add a field on your search card for searching by content which will find properties in the file. This works for SolidWorks and Office files well. You have to setup ifilters for other file types though.
The Complete search card has a tab for content searching.
