Hello @Shankar_K ,
> Architecture:
AEM Publish → Indexer Service → Elastic Cloud (pages, assets, fragments, suggest)
Search API → UI. Do NOT use AEM QueryBuilder for site search.
> Indexing (AEM → Elastic):
- Index only published content.
- Fields: path, url, title, summary, bodyText (HTML stripped), tags, locale, site, publishDate.
- Assets: title, tags, mimetype, metadata.
- Trigger on Activate/Deactivate. Retry queue. One-time full backfill.
> Analyzers:
- Language analyzers per locale.
- Lowercase, asciifolding.
- Synonyms (versioned).

Pitfalls:
- Don’t connect Elastic directly to QueryBuilder.
- Don’t overshard.
- Avoid indexing Author content.
