We are trying to index a file (word document) which is \> 45 MB . It is failing throwing an exception as below: Maximum timeout reached while retrying request. Call: Status code unknown from: PUT /test\_index6/\_doc/16601?pipeline=Attachment What is the maximum file size recommendation and how do we increase the size limit to handle large file indexing? ---

There are some limits like no more than 100mb for a single HTTP request. 45mb of binary data can become much bigger when you BASE64 encode it. So be careful with that. That's one of the reason I prefer to extract the text and metadata before sending it to elasticsearch. That's what FSCrawler project does basically. Disclaimer: I'm the author of FSCrawler. ---

Thanks David. As per this link from elastic :[General recommendations | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/general-recommendations.html#:~:text=Avoid%20large%20documentsedit&text=max_content_length%20is%20set%20to%20100MB,documents%20are%20usually%20not%20practical) we added http.max\_content\_length set to 350 mb in the yml file but no luck. It says custom limit is 2 GB. Am I getting it wrong? ---

What are Elasticsearch logs and the full trace of the error? ---

We increased the http\_max\_content\_length to 350 mb, but we still the issue with that. Also, when we check elasticsearch.log within the server, don't see much details. Hope this would help. ---

Could it be a client side error? ---
