A search query is usually too complex to get the desired result with a single search term. You have to use multiple search terms and combine them.
Suppose: you are interested in climate change and migration.
You want to find literature on this topic.
Identify the key elements:
climate change and migration
By cleverly combining your search terms, you only need to perform one search:
(“climate change” OR “climate crisis”) AND (migration OR refugee* OR “people on the move”)
Broader Terms: | Climate | Human Response |
Related terms: |
climate change climate crisis |
migration refugees people on the move |
More specific terms: | global warming |
climate refugees environmental refugees |

Example: |

Combine search terms to find less results | AND |
T1 AND T2 |

T1 NOT T2 |
Tip: all databases work with different interfaces, search options and for instance different symbols for wildcards. Look at the Help pages, to find out about specific functions.
