Keyword Search Help

Basic searching

You may enter one or more words into the keyword search field in order to find the images/files you are looking for.

If you enter more than one word into the keyword search field then the search will find items that contain all of the words you entered.

The search is not case sensitive, with the exception of the boolean operators described below.

Searching for phrases

You can search for a phrase of two or more words by enclosing the words in quotation marks. E.g. searching for

"the pink panther"

will find only items containing this complete phrase.

Boolean operators

AND

Placing the operator AND (in upper-case) between two words or phrases will find only those items that contain both words or phrases. E.g. searching for

return AND "pink panther"

will find only those items containing both the word "return" and the phrase "pink panther".

The AND operator is optional; leaving a space between 2 words or phrases has the same effect.

OR

Placing the operator OR (in upper-case) between two words or phrases will find items that contain either of the words or phrases. E.g. searching for

return OR "pink panther"

will find items containing either the word "return" or the phrase "pink panther".

NOT

Placing the operator NOT between two words or phrases will find only those items that contain the first word or phrase but do not contin the second. E.g. searching for

pink NOT red

will match items that contain the word "pink" but do not also contain the word "red". Note that there must be a word or phrase on either side of the NOT operator.

Grouping

Parentheses can be used to group search clauses into sub-queries. This can be very useful for controlling the boolean logic of a search. For example, the search

red AND pink OR blue

is logically ambiguous, whereas the meaning of

red AND (pink OR blue)

or

(red AND pink) OR blue

is clear.

Wildcard searches

Wildcards can be used to match against any character or characters that appear somewhere in a word. Note, however, that neither of the wildcards described below can appear at the beginning of a word - at least the first character of the word must be specified.

Single character wildcard

A question mark (?) can be used in a word to match against any single character. For instance,

p?nk

will find "pink" and "punk".

Multiple character wildcard

An asterisk (*) can be used to match any 0 or more characters in a word. For instance,

pin*

will match "pin", "pink", "pints", etc. and

p*t

will match all word beginning in "p" and ending in "t".
