## Search strategies

Have you found something that is already quite relevant and useful? You can use that as a starting point to look for more material.

Database search
Typing search terms in a search entry and looking at what comes out, that is called the bibliographic method. Study the results you get with a search and then formulate a better query. Also look at the technical terms used in the relevant articles you already found.

Snowball method
A well-founded publication will refer to other sources to indicate where they got their information. Maybe those sources are also suitable for your problem. Note: An article will only refer to previous publications, so you will only find older articles.

Citation search
Some search engines and databases can also show which newer articles refer to the article you found. The reverse of the snowball method: which articles have used the item you found in the references list? This way you can find more recent, related articles.
