        .DESCRIPTION
            This function uses the search ability of Plex find items on your Plex server.

            an option to refine this by type.
        .PARAMETER ItemName
            Name of what you wish to find.
        .PARAMETER ItemType
            Refines the output by type.
        .PARAMETER Year
            Refine by year.
        .PARAMETER ExactNameMatch
            Return only items matching exactly what is specified as ItemName.
        .EXAMPLE
            # Find only 'movies' from the Plex server that (fuzzy)match 'The Dark Knight'.
            Find-PlexItem -ItemName 'The Dark Knight' -ItemType 'movie'
        .EXAMPLE
            # Find items that match exactly 'The Dark Knight' from the library 'Films'.
            Find-PlexItem -ItemName 'The Dark Knight' -ExactNameMatch -LibraryTitle 'Films'
        .EXAMPLE
            # Find items that (fuzzy)match 'Spider' from the library 'TV'.
            Find-PlexItem -ItemName 'spider' -LibraryTitle 'TV'
