If you only have access to the Oracle Database 12c Release 1 (12.1) Online Documentation Library, you can browse the error messages by range. Once you find the specific range, use your browser's "find in page" feature to locate the specific message. When connected to the Internet, you can search for a specific error message using the error message search feature of the Oracle online documentation.

Many books in the documentation set use the sample schemas of the seed database, which is installed by default when you install Oracle. For information about how these schemas were created and how you can use them yourself, see Oracle Database Sample Schemas.
