search: search string
text: search field
start: starting byte position, defaults to 1
search may contain wildcard characters (*) and question marks (?). A question mark matches any single character, and a wildcard matches any string including the empty string. To search for * or ?, precede the symbol with ~.
This search is not case sensitive. If search is not found, SEARCHB returns #VALUE! If start is less than one or it is greater than the byte length of text, SEARCHB returns #VALUE! The semantics of this function is subject to change as various applications implement it.
While this function is syntactically Excel compatible, the differences in the underlying text encoding will usually yield different results.
While this function is OpenFormula compatible, most of its behavior is, at this time, implementation specific.
