How-to-Google

General

Keep the Google search as simple as possible only being specific where necessary
Gradually add search terms, if you do not get good results
Try to search with professional terms, instead of natural speaking language
Only use important words, instead of full sentences
Use descriptive words and simply rephrase searches, if no good results show up
Use quotes around your search words "search words", to tell Google to use exact matching for the text within quotes, asterisks * can be used as wildcards to match any text
Use hyphens <ambiguous search> -<one matching field> to explicitly tell Google to exclude words from the search

Just copy the error message from the command line to the Google search bar
Remove system specific details like the system name or paths
Though you should keep the file name, if it corresponds to a provided or system source code file
