The * wildcard character can appear on its own and implies Google-style. The "anywhere after" wildcard pattern can be combined with the = prefix for identifier based pattern matching. Search will return and highlight any word that begins with the root of the word truncated by the * wildcard character.
The following will all find the term apple.
TEXT:app?e TEXT:app* TEXT:*pple appl? *ple =*ple "ap*le" "***le" "?????"
When performing a search that includes a wildcard character, it is best to wrap your search term in double quotation marks. This ensures all metadata and content are searched.
