Question

Answer

Starting a query

Click the keyboard icon in the search query bar

Searching for a single term

Type the term you're interested in (e.g. vaccine) in the search query bar

Searching for multiple terms

You can use either the logical operator (e.g. AND/OR) between each term or you can use commas to indicate the same relation (like writing a sentence). E.g COVID and vaccine / COVID, pfizer and vaccine / COVID and pfizer and vaccine

Excluding terms

Type either not or but not before the term or terms you want to exclude. E.g. COVID, pfizer and vaccine but not astrazeneca / COVID, pfizer and vaccine not astrazeneca / COVID, pfizer and vaccine but not (astrazeneca or AZ)

Grouping logic together

You can group terms together using brackets. E.g. (COVID, virus or coronavirus) and vaccine

Labelling groups

You can indicate the label by using square brackets after the group and writing the name of the label in quotes. E.g. (COVID, virus or coronavirus)["Virus"] and vaccine

Searching for a literal term

You need to type the literal term in quotes. This is useful if you want to use a sepcial word like 'and'. E.g. "Johnson and Johnson"

Specify a token type to search against

You can specify a specific token type followed by : before the term you're looing for. E.g. source: BBC and title: Pfizer. If you don't specify a token type, it defaults to 'keyword' type

Proximity searching

To specify a proximity search you need to use a tilda with a number after the terms in question. E.g. hello world ~ 5. This will allow hello and world to appear no more than 5 words apart

Prefix searching

To sepcify a proximity search you need to use an asterisk after the word, partial word or words you want to attach the prefix to. E.g. corona* this will return everything that matches after this stem of the word e.g. corona, coronavirus, coronaviruses, etc...
