Indexing issue ?

[vool]

I have a query re the operation of the tntsearch:import command where it does not seem to be indexing my models correctly,

I have a published key on my model I only want models indexed if published is set.

When I update the model or run scout:import they are indexed correctly but when I run tntsearch:import models are indexed regardless of published

Or is this the correct operation of tntsearch:import

Below is my toSearchableArray

public function toSearchableArray()
    {

        // only add to search index if story is published and approved

        if ($this->published) {

            $array = $this->toArray();

        }else{

            $this->unsearchable();

            $array = [];

        }

        return $array;
    }
