## Description

This project provides a SQL interface for Elasticsearch, serving as a translator and database layer that allows users to retrieve, filter, and manipulate indices using structured query language. It functions by converting standard SQL statements into the native JSON query language used by the search engine.

The system includes a geospatial SQL engine for executing location-based searches and distance calculations. It also features a query debugger used to visualize the translation process from SQL to search engine request bodies to verify the logic and accuracy of data retrieval.

The capability surface covers data retrieval and record management, including the deletion of specific data entries. It further supports data analysis through large-scale aggregations, statistical summaries, and data transformations using conditional logic and mathematical functions.
