[Array->FindIndex] searches the array for the parameter and returns an array of indices for those elements which match. Accepts a single parameter of any data type.
If the array contains any pair values, only the first part of the pair is compared with the parameter of the [Array->FindIndex] tag.
If no elements in the array match the parameter to the [Array->FindIndex] tag then an empty array is returned.
[Array->(FindIndex: 'Find Value')]

This tag was deprecated in favor of [Array->FindPosition].
To find the index of a certain value within an array:
Use the [Array->FindIndex] tag. This tag can be used to locate the index of a particular value within an array so that element can be deleted or changed.
In the following example the index for the item Blue is found and the value of that element is changed to Aqua.
[Variable: 'myArray' = (Array: 'Red', 'Green', 'Blue', 'Orange')]
[Variable: 'myIndex' = $myArray->(FindIndex: 'Blue')->(Get:1)]
[$myArray->(Get: $myIndex) = 'Aqua']
[Output: $myArray]
(Array: (Red), (Green), (Aqua), (Orange))
