Returns the first index less than
position 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
|position ||where search is to start from. If position is less than or greater than the text range for searching, an U_INDEX_OUTOFBOUNDS_ERROR will be returned |
|status ||for errors if it occurs |
- The character index of the first match preceding
USEARCH_DONE if there are no matches.
