Apache solr custom request handler implementation

Hi Experts,

Hybris version:-6.3.0.2

I want to create my custom handler for solr search. Default request handler is "/select" but i want to implement my own implementation as i have parameterize query which is to be indexed.

Could anybody please tell me how can i implement the same in Hybris? Please share any reference implementation or documentation for the same.

Thanks & Regards,
