Search Help

The Search engine supports "AND", "+", "OR", "NOT" and "-" as Boolean operators. The words "AND", "OR" or "NOT" must be in ALL CAPS. Phrase searches are also supported.

Phrase searches

Enclose phrases in double quotes to search for a phrase.

Example: "teenage pregnancy statistics"


By default "OR" is used for two or more terms. This means that if there is no Boolean operator between two terms the search engine links the two terms and finds a matching document if either of the terms exist in a document. The symbol || can be used in place of the word OR.

These two queries are equivalent:

Misoprostol Mifepristone

Misoprostol OR Mifepristone


"AND" matches documents where both terms exist anywhere in the text of a single document. The symbol && can be used in place of the word "AND".


Ghana AND "access to services"


The "+" symbol requires that the term after the "+" symbol exist somewhere in a field of a single document.

To search for documents that must contain "misoprostol" and may contain "mifepristone" use the query:

+misoprostol mifepristone

"NOT", "-"

The "-" or "prohibit" symbol excludes documents that contain the term after the "-" symbol.

To search for documents that contain "misoprostol" but not "mifepristone" use the query:

misoprostol -mifepristone

or alternatively:

or alternatively:

misoprostol NOT mifepristone
