You can search for your topic using Summon. You may wish to limit your search to Scholarly & Peer Review.
You can also search one of these specialized databases to find journal articles and grey literature (e.g. conference proceedings, government and NGO reports, theses & dissertations). They offer more functionality than Summon.
Wildcards are signs that stand in for a letter and allow you to search various spellings. For example:
col?r searches for "color" and "colour"
Note: the question mark is used for the UBC Library catalogue, but other databases may use other symbols such as ?, #, and $.
See this wiki page for a more comprehensive guide.
Google can be useful for searching the websites of government, non-governmental organizations (NGOs), community groups and companies to find press releases, reports, etc.
