Array

Here you will find the array passed through from the Array input of the node.

Here you receive the result of the check as a bool value. The result is true if the element you are looking for is present in the array and false if it is not.

First Index[-2147483648..2147483647]

If the value you are looking for is found in the array, you can read out the smallest index number at which the value is stored here. You can find out whether the value can be found more than once in the array using the following Lndex List output.

Index

Here you get an array that contains all indices where the Value was found. To find out how often the value is present in the array, you only need a Get Count node to output the length of the Index List array.
