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

Any combination of Boolean operators is allowed. Example:
Grouping is possible by use of parentheses. Example:

WILD CARDS / TRUNCATION / FUZZY SEARCHES

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