Returns the index i (starting from 1) of the leftmost found needle i in the string haystack and 0 otherwise.įor a case-insensitive search or/and in UTF-8 format use functions multiSearchFirstIndexCaseInsensitive, multiSearchFirstIndexUTF8, multiSearchFirstIndexCaseInsensitiveUTF8.
The same as position but returns the leftmost offset of the string haystack that is matched to some of the needles.įor a case-insensitive search or/and in UTF-8 format use functions multiSearchFirstPositionCaseInsensitive, multiSearchFirstPositionUTF8, multiSearchFirstPositionCaseInsensitiveUTF8.
