Searching Syntax and Operations

Boolean Operators

You can use the Boolean operators AND, OR or NOT in searching. Without these Boolean operators the words are and'ed together. The operators are not case sensitive. These three searches are the same:

labor market
market labor
labor AND market

The not operator inverts the results of a search.
Parentheses can be used to group searches.

not (labor AND market)

To search for the words and, or, or not, place them in double quotes.

Migration "and" labor markets

will find any page containing one of the four words.

Truncation

The wildcard (*) is available, however it can only be used at the end of a word: otherwise it is considered to be a normal character.

econom*

retrieves "economic", "economics", "economical", etc.

Phrase Searching

To search for a phrase in a document use double-quotes to delimit your search terms.

"International Migration"
