function New-Neo4jIndex {
    <#
    .SYNOPSIS
       Add indexes to Neo4j properties

    .DESCRIPTION
       Add indexes to Neo4j properties

    .EXAMPLE
        New-Neo4jIndex -Label Server -Property computername, domain -Composite

        # Add a composite index on the 'computername' and 'domain' properties for nodes labeled 'Server'

    .EXAMPLE
        New-Neo4jIndex -Label Server -Property computername, domain

        # Add individual indexes on the 'computername' and 'domain' properties for nodes labeled 'Server'

    .PARAMETER Label
        Label containing the property we want to index

        Warning: susceptible to query injection

    .PARAMETER Property
        One or more properties to create indexes on

        The 'Composite' parameter specifies whether to create an index per property, or a composite index on multiple properties

        Warning: susceptible to query injection

    .PARAMETER Composite
        If specified and more than one property is specified, create a composite index

        If *not* specified and more than one property is specified, an index is created per property

    .PARAMETER As
        Parse the Neo4j response as...
            Parsed: We attempt to parse the output into friendlier PowerShell objects
                     Please open an issue if you see unexpected output with this
            Raw: We don't touch the response ($Response)
            Results: We expand the 'results' property on the response ($Response.results)
            Row: We expand the 'row' property on the responses results ($Response.results.data.row)

        We default to the value specified by Set-PSNeo4jConfiguration (Initially, 'Parsed')

        See ConvertFrom-Neo4jResponse for implementation details

    .PARAMETER MetaProperties
        Merge zero or any combination of these corresponding meta properties in the results: 'id', 'type', 'deleted'

        We default to the value specified by Set-PSNeo4jConfiguration (Initially, 'type')

    .PARAMETER MergePrefix
        If any MetaProperties are specified, we add this prefix to avoid clobbering existing neo4j properties

        We default to the value specified by Set-PSNeo4jConfiguration (Initially, 'Neo4j')

    .PARAMETER BaseUri
        BaseUri to build REST endpoint Uris from

        We default to the value specified by Set-PSNeo4jConfiguration (Initially, 'http://127.0.0.1:7474')

    .PARAMETER Credential
        PSCredential to use for auth

        We default to the value specified by Set-PSNeo4jConfiguration (Initially, neo4j:neo4j)
