I have customized out of the box index cqPageLucene and the new index node name is cqPageLucene-custom-1.
But still it is picking cqPageLucene not the custom index.
Even I tried using index node name as cqPageLucene-1-custom-1.
I have followed following document

Let me know if further changes needed
thanks in advance
