+   * Resolve the supplied index alias into the actual Elasticsearch / OpenSearch index name to
+   * query. Handles four shapes:
+   *
+   * <ul>
+   *   <li><b>Entity-specific alias</b> (e.g. {@code "table"}): looked up in
+   *       {@code entityIndexMap} and resolved to the canonical {@code *_search_index} name.
+   *       This is the bug fix — without resolving, ES would treat {@code "table"} as an alias
+   *       and expand it to every index that has that alias attached, including
+   *       {@code column_search_index} (because {@code tableColumn} declares {@code "table"} as
+   *       a {@code parentAlias}). Resolving here bypasses ES's alias expansion entirely so a
+   *       query for tables only hits the table index.
+   *   <li><b>Compound alias</b> (e.g. {@code "all"}, {@code "dataAsset"}): no entry in
+   *       {@code entityIndexMap}, no canonical index, so the alias passes through and ES
+   *       resolves it natively across the entities that have registered the alias. This is the
+   *       intended behavior — searching {@code dataAsset} should surface every data-asset
+   *       entity.
+   *   <li><b>Canonical / legacy index name</b> (e.g. {@code "table_search_index"}): not a key
+   *       in {@code entityIndexMap}, falls through to the prefix-and-pass branch, identical to
+   *       the legacy behavior.
+   *   <li><b>Already cluster-prefixed token</b>: idempotent — returned unchanged so that
+   *       internal code paths that hand back a resolved value don't double-prefix.
+   * </ul>
+   *
+   * Comma-separated tokens are resolved independently. Empty tokens (from {@code "table,"} or
+   * {@code ","}) are dropped instead of materializing as a bare cluster prefix; if every token
+   * is empty the original input is returned unchanged so downstream ES surfaces a normal
+   * "unknown index" error instead of an empty-target failure.
