Is it possible to modify search fragment in Confluence cloud?

Hello Everyone,

I am looking to integrate external document management system with confluence. When user searches in confluence he should see results from external systems as well and shown in consolidated search results. Is that something which is possible ?
If not than what are possible workarounds to it ?

@VishwajeetSingh The native search function and search results do not provide the ability for you to perform that kind of external system integration; however, you can see on the Marketplace that there are apps that do provide advanced / integrated search capabilities… all of which likely utilize the search API.

Thanks that leaves me with choice of creating a separate search interface .
