Website Search / Elastic Search / Redisearch / meilisearch

We need self hosted Elastic Search / Redisearch / meilisearch based custom site search script for static html website / dynamic websites.

Font-end:
1) Image with text result
2) Tab by site index: (Group1, Group2, Grup3, Group4)
3) Typo Tolerance, instant results (while typing...)
4) Multiple front-ends group wise and site-wise. (Ex: Option to add abc.com and show only abc.com results on abc.com and also abc.info, aaa.co group comes under abc corp and that results will show separately.)

Just like google custom search / Programmable Search Engine.

Back end:
1) Login Page
2) On the admin panel user can able to add/remove/change the site url and able to add multiple site url's
ex: abc.com, nxz.com, test.com - (group 1) and ynx.com (Group 2) like that
3) can able to add .xml sitemaps, automatic web crawler / crawler frequency update
4) Number of indexed files, maintenance mode option.

NOTE: Those who have experience with elastic search / web search / similar project only.

NO NEW FREELANCERS / INDIAN FREELANCERS please.
