With our migration to Online Documentation, you can search the documentation with any modern browser. This search utility supports sub-string searching (magnet will result in magnetics, magnets etc.) This search engine will give weight results with priority on the title of the topic, and the content second.
If you are familiar with the documentation of INTREPID then the Table of Contents above will provide you a way to explore the topic tree directly into the Tool References/General References/Cookbooks or Guided Tours sections.
Alternatively, navigate to support topics by using the library pages split into disciplines of geophysics/intent of the content.
