Search result is not shown for public search

(from github.com/PakanAngel)
Hi,
I just setup Elasaticsearch with Fess on Centos 7 env. I’ve defined several crawlers for indexing some websites which are working properly. When I search in admin panel for some specific keywords can browse the those search results very well but when I am searching the same keywords as guest on public search page, no search results is shown. How can I let my customers search through the main search page without any issue? Am I missing any configurations after the installation?
Please help

What is your crawling configuration?
Did you change Permission?

Thnx for your quick response. It was my own fault just excluded guest role from admin user.
