    /**
   * Inserts a document identifier into one or more index files as defined by the global index meta.
   *
   * OPTIMIZED: Uses in-memory index cache for fast reads and atomic dual-write (memory + disk).
   *
   * The method:
   * 1. Calls `this.findMatchingIndexMeta(document)` to determine which index files should be updated.
   * 2. For each matched index entry:
   *    - Gets current index data from memory cache (or loads from disk if not cached)
   *    - Appends `${document.documentId}${General.DBMS_File_EXT}` to `indexEntries`
   *    - Updates both memory cache and disk atomically via indexCache.updateIndex()
   *
   * @param document - Object representing the document to index. Must contain a `documentId` property (string | number).
   * @returns A Promise that resolves to:
   *  - `true` if the last index file write operation returned a success status,
   *  - `false` if the global index meta could not be read, no matching index meta entries were found, or the final write returned a falsy status.
   *
   * @throws Propagates any exceptions thrown by file reads/writes or conversion (e.g., IO or parse/serialize errors).
   *
   * @remarks
   * - Updates both memory cache and disk atomically
   * - Thread-safe via index cache locking mechanism
   * - Falls back to disk read on cache miss (cold start recovery)
   *
   * @example
   * // document must include documentId:
   * // { documentId: "abc123", ... }
   * const success = await indexService.InsertToIndex({ documentId: "abc123" });
