Adjacent wildcards are not supported. Adjacent '*' wildcards are meaningless, and thus are not allowed.
Perform a query using single wildcards.
* matches zero or more characters.
This wildcard is useful when you are not sure what you are looking for, but have a general idea. It expands a search term to include all forms of a root word, e.g., patent* retrieves patent, patents, patentable, patented, etc.
