Get Best results in Google using Wildcards- Google Tips

[ar]

A wildcard in a Google search query can be indicated by an asterisk (*), and will match one or more whole words.
Example: A search for [ cooking * classes ] will return results for all of the following phrases (and more):
"cooking school classes"
"cooking and tasting classes"
Onecommon use of the asterisk is to fill in the blanks for a query thatanswers a question: [ the parachute was invented by * ]. Also, you canuse more than one asterisk in a single search, such as [ vitamin * isgood for * ].
Wildcard searches work for whole words or phrasesonly. Currently, Google doesn't support searches in which an asteriskindicates a fraction or extension of a word, for example, [ flower *classes ] won't match "flowerful classes."
However, Google douse stemming technology — when appropriate, Google will search not onlyfor your search terms, but also for words that are similar to some orall of those terms, for example, if you search for [ pet lemur dietaryneeds ], Google will search for the term and also other relatedvariations of your terms.
