/**
 * Elasticsearch Text Store (FUTURE FEATURE)
 *
 * This is a stub implementation for future Elasticsearch integration.
 * When implemented, it will provide:
 * - Distributed full-text search
 * - Advanced query DSL
 * - Synonym support via synonym filters
 * - Scalable indexing for large codebases
 *
 * IMPLEMENTATION STATUS: Stub - Not yet functional
 *
 * To implement:
 * 1. Install @elastic/elasticsearch package
 * 2. Set up Docker Compose with Elasticsearch
 * 3. Implement the methods below
 *
 * Docker Compose example:
 * ```yaml
 * services:
 *   elasticsearch:
 *     image: docker.elastic.co/elasticsearch/elasticsearch:8.11.0
 *     environment:
 *       - discovery.type=single-node
 *       - xpack.security.enabled=false
 *       - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
 *     ports:
 *       - "9200:9200"
 *     volumes:
 *       - elasticsearch-data:/usr/share/elasticsearch/data
 *
 * volumes:
 *   elasticsearch-data:
 * ```
