Here's a nice search tip: When you're searching in Google, you can limit the search to a specific site, such as Thwack or the SolarWinds Success Center. Add "site:<siteURL>" to the beginning of your search, followed by your search terms.
Example 1 limits the search to Thwack:
site:thwack.solarwinds.com npm upgrade
Example 2 limits the search to Thwack and includes Boolean operators:
site:thwack.solarwinds.com npm AND (upgrade OR migrate)
