How to broaden a search

If you have not retrieved the information you expected, you may need to broaden your search.

Check that you need all the terms in the search. Delete any unnecessary terms from the search box and re-run the search.

Is one of your terms too specific? Many drug names are members of one or more broader groups. Use the thesaurus display to select a broader term.

• Click the symbol next to a term to display its relationships.
• Click the symbol next to 'Broader terms' and 'Related terms' (if available) to expand the display.
• Click on an appropriate broader or related term. The term selected will replace the original term in the search.
• Search will be re-run automatically.
• Repeat this process to broaden the terms further if required.

Notes:

If a group term is selected both that term and all of its related narrower terms will be included in the search. The highlighting colour shows which family a hit belongs to.
