Searcher

Overview

Module

• package: org.eclipse.dirigible.sdk.indexing
• source: indexing/Searcher.java

Full-text search over the documents previously indexed via Writer. The query string uses Lucene query syntax — field-qualified (title:invoice), boolean (title:invoice AND status:open), wildcard (invoice*), fuzzy (invoice~). Results are returned as a JSON document with location, content excerpt, and metadata for each hit.

Indexes are named so the same JVM can host multiple corpora (products, orders, docs); the index name on every call selects which corpus to search.

Key Features:

• Lucene query syntax — boolean, wildcard, fuzzy, field-qualified.
• Multi-corpus — name-isolated indexes share one JVM.
• JSON output — easy to forward straight into a controller response.

Example Usage:

import org.eclipse.dirigible.sdk.indexing.Searcher;

String hits = Searcher.search("products", "title:headphones AND status:active");
