Magento 2 Software Recommendations
We require the following software for production instances of Commerce:
Nginx and PHP-FPM
Elasticsearch or OpenSearch
For multi-server deployments, or for merchants planning on scaling their business, we recommend the following:
Redis for sessions (from 2.0.6+)
A separate Redis instance as your default cache (do not use this instance for page cache)
See system requirements for information about supported versions of each type of software.

Magento 2 without ElasticSearch
Legacy Mysql Search Extension for Magento 2 allows you installing and work with Magento 2.4.x without ElasticSearch enabled.
This is simple and very useful solution for low cost hosting plans and non-big data in categories and products filters.
Simple for simple.
Huge thanks to the authors.
