int32_t SearchIterator::first ( UErrorCode status  )  [inherited]

Returns the first index at which the string text matches the search pattern. The iterator is adjusted so that its current index (as returned by getOffset) is the match position if one was found. If a match is not found, USEARCH_DONE will be returned and the iterator will be adjusted to the index USEARCH_DONE

Parameters:
status for errors if it occurs
Returns:
The character index of the first match, or USEARCH_DONE if there are no matches.
