Does not exist (false).
indexOfStart position of the found text.Not Case-sensitive.


indexOf('<text>', '<searchText>')
textRequired fieldTarget text.
searchTextRequired fieldText to be searched.

You can change the contents of the function by clicking on the purple icon.

If we use indexOf('abcde','bcd') as in the example,The result is 1 because 'bcd' is the second character.

indexOf('aBcde','bCd') is also case-insensitive, so the result is the same.

If found at the beginning, 0 is the result.

If no match is found, the result is -1.

If there are multiple matches, the result of the first match (left most) is retrieved.
