Quick help guide


There are a number of ways to perform a search across the site. You can search using the main search box on every page.

You simply describe the subject of your search as you would in any popular search engine. You can also perform more complex searches here using Boolean logic (AND, OR, NOT) N.B. always place the Boolean logic in uppercase / capital letters).

Use quotes to search for an exact set of words, e.g. "carbon emissions".

You can also use bracketing so that certain parts of your search are performed together e.g. ("climate change" OR "global warming") AND "habitat loss".

To exclude certain types of publication, use the 'filter by type' dropdown menu.


Topic Pages

Near the top of the page (below the CABI logo) there are buttons that take you to topic pages, which focus on information relevant to each topic.

When you go to a particular topic page (e.g. clinical nutrtion) any search is automatically limited to that particular topic (as defined by our subject experts). To search within other topic areas click the "search within topic" box and select the appropriate topic you wish to search. If all boxes are deselected then a complete site search is performed.

On the search results page filter your search further by adding additional terms from the right hand column.

Smart Searches

These are searches on key topics created by our experts to save you time. We will create new Smart Searches if you request them and these will be made available to all users from this tab. 


This feature offers a personalised workspace where you can:

  • Save and export records
  • Save your searches
  • Subscribe to saved searches via RSS and email alerts to ensure you receive the latest updates.
