Technology Domain

There are 35 technology domains in English created by Questel based on IPC classes and subclasses. The list of domains can be viewed using the  button.

The domains are distributed among Chemistry, Electrical Engineering, Instruments, Mechanical Engineering, and Other. You can select whichever domains you want to search in, and they will be added to your keyword and/or classification search.

The Confirm button transfers the selected domains into the input line. The domains are placed in quotes (an expression search for as-is) and separated by an automatic OR operator. You can edit the OR and replace it with a different Boolean operator (AND or NOT).

The Cancel button closes the assistant without searching domains.
