Hi, I'd like to search for a substring in the message field of my document, but I can't get it done. The substring is "Error while initializing socket". I'd like to get it via curl. I already search a lot in the documentation and while trying I always get the wrong documents back. ---

Could you provide a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will help to better understand what you are doing. Please, try to keep the example as simple as possible. A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer. ---
