General search techniques that can be used in most databases and search engines are briefly described below.
Subject headings
In various databases, subject headings are assigned to publications. These concisely describe what the publication is about. The subject headings make it possible to search for a topic.
Fillers
Fillers are words that are common, but not important for a search. Examples of these are determiners and prepositions.
Combining search terms
Combining multiple topics in one search can be done with Boolean operators. The main operators are AND, OR and NOT:
AND
All specified terms must appear in the search result.
OR
One, or both, of the specified terms must appear in the search result.
NOT
The specified term must not appear in the search result.
Nesting terms
With more complex searches, it can be efficient to nest search terms using brackets.
Example: swallow AND (spring OR summer)
Phrase searching
Double quotes around a phrase ("...") indicate that the specified search terms must be side by side in this exact order.
Examples: "elementary education", "social media"
