Hi,

Thank you for your response. I attempted to utilize an ingest pipeline for App Search Web Crawler, but unfortunately, it didn't produce the desired results. I discovered that the App Search Web Crawler engine has its own dedicated ingest pipeline specifically designed for binary documents, excluding HTML. [Ingest pipeline for App Search document indexing](https://discuss.elastic.co/t/ingest-pipeline-for-app-search-document-indexing/310337). It seems that custom fields cannot be ingested into HTML documents using this pipeline. 🤔
