Portal - Full Text Search Web Service

Purpose

The purpose of this service is to be your full text search web service for any JSON client including JavaScript front-ends like React with fetch.

Portal is a competitor to ElasticSearch, MeiliSearch, AWS CloudSearch, AWS ElasticSearch Service, and Algolia.

Portal is built to be simple and blazing fast with JWT verification, indexing, deindexing, search, and word suggest.

Indexing is batch indexing by default.

To use this service you need to have a running sonic server and a broker server.

• Very performant with almost no CPU and memory usage
• Supports full-text search and word suggestions in 87 natural languages
• Under 1000 lines of code
• Supports CORS

• Supports JWT caching with expiry checking to minimize verify API calls
• Multi-tenant
• Supports SSL - full end-to-end encryption
• JSON API
• Auto-provision and renews SSL cert via LetsEncrypt or use your own SSL cert
• Uses user authorization scoping
• Built on sonic and broker
