Functionality
-------------
This node searches items in given data and returns their indexes. It's equivalent to `list.index` method in Python.

Category
--------

List -> List main -> List Index

Inputs
------

* **data** - where to search items
* **Item** - what to search in data

In use range mode:

* **Start index** - index from which to start searching (inclusive)
* **End index** - index where to finish searching (exclusive)

Outputs
-------

* **Index** - An index of an item in data. If there is no such item -1 value will be returned.

Options
-------

- **Level** - Level of data where to search items. With level 2 it will search in nested list of main one.
- **Use range** - It adds two extra sockets for specifying a range where to search items in given data.

Examples
--------

**Finding index of maximum value in array of random values**
