Search specific fields

  There must be no spaces between the ':' and your search term. For example, a search for title:bird will work, but title: bird will not.
Search termExampleSearches for
title: title:Windermere Returns results which contain the word Windermere in the title of the data resource
description: description:lake Returns results which contain the word lake in the description of the data resource
keywords: keywords:Wales Returns results which contain the keyword Wales

These searches match whole words by default, so searching keywords:biodiversity will return records but keywords:bio will return no results.

To match partial searches, you can include wildcards. For example, keywords:*bio* will return records with keywords biodiversity, biochemistry, biomass and microbiology

Combining terms

The rules described above can be combined to create complex searches. For example:

title:biodiversity AND title:Wales
finds records with the both the words biodiversity and Wales in the title

title:biodiversity AND Wales
finds records with the word biodiversity in the title and which contains the word Wales anywhere in the record

title:night NOT description:day
finds records with the word night in the title but omit any records with the word day in the description

description:*land
finds records in which the description contains any word ending with land (e.g land; marshland; woodland; Scotland)

Parentheses can be used to group terms:

Wales AND (otter OR badger)
finds records with the word Wales which also contains either the word otter or the word badger

Parentheses can also be used to group field searches, for example title:otter AND title:Wales can also be written as title:(otter AND Wales)
