STANDARD (DEFAULT) SEARCH USES "AND" OPERATOR, EXACT SEARCH

Exact word search is ON. See section WILD CARDS. AND is default Operator. See section BOOLEAN OPERATORS below.

CustomsMobile’s Regulations search engine by default performs exact searches. It also treats two or more searched words as if connected with AND. Example:

fish origin

Returns only regulations containing fish AND origin. Also does not include fishes, fishing, origination, etc. See section WILD CARDS below.

BOOLEAN OPERATORS (MUST BE CAPITALIZED)

CustomsMobile Regulations by default performs an AND search when two or more terms are specified and no Boolean operators are used.

AND

fish AND origin

Returns only regulations containing both fish and origin (default)

fish OR origin

Returns regulations containing either fish or origin

NOT

fish NOT origin

Returns only regulations containing fish but not origin

Any combination of Boolean operators is allowed. Example:

broker AND examination AND days NOT cargo NOT taxpayer

Grouping is possible by use of parentheses. Example:

(broker AND examination AND days) NOT (cargo OR taxpayer) NOT markets

WILD CARDS / TRUNCATION / FUZZY SEARCHES

Exact word search is ON. You must use wildcards or fuzzy searches for results other than exact matches.

Regulations Mobile allows various types of approximation searches:

fish* finds: fish, fisher, fishing, etc.

The asterisk (*) finds any no. of characters. It can be placed anywhere in the word.

??FTA finds: NAFTA, UKFTA, AUFTA, etc.

Each question mark (?) finds one character. There is no limit to the number of question mark(s), they need not be adjacent, and can be placed anywhere in the word.

fish~.7 finds: wish, fish

Following search term with ~n returns similarly spelled words. "n" ranges from 0 (least similar) to 1 (most similar). Default is 0.5.

You may combine any Boolean operator & Wild Card:

fis? NOT (fish OR fisk)

[Alternate: fis? NOT fish NOT fisk ]

Canada^7 NAFTA
