- How can I search so efficiently in very large plain text file?
- How can I efficiently search for a specific string in a large text file using C#?
- I built an advanced search system for my data. Like ElasticSearch. But I was considering using a third-party service like this that's cheap. Is ElasticSearch or another service in Azure ideal for this?

Murmur3 hash plugin for nested objects?
I don't think the murmur3 hash implementation has changed since it was added as the default in version 2.0 (see the [changes](https://github.com/elastic/elasticsearch/commits/main/server/src/main/java/org/elasticsearch/cluster/routing/Murmur3HashFunction.java)). The plugin itself has seen [more changes](https://github.com/elastic/elasticsearch/commits/main/plugins/mapper-murmur3) but that's IMO because of internals and not visible changes in the calculations.
