Project mention: Ask HN: What you up to? (Who doesn't want to be hired?) | news.ycombinator.com | 2021-11-01
I have slowly collected a large (several million file) ebook library from open directories over the past few years. I am now trying to set up a search solution for it.
Recoll doesn't seem to work well headless, so I am taking a look at: https://github.com/ICIJ/datashare
which claims to be able to do some distributed indexing.

java-specialagent
Automatic instrumentation for 3rd-party libraries in Java applications with OpenTracing.
Amongst the treasures found within the opentracing-contrib project is a Java special agent. By plugging this into our app via the -javaagent JVM flag we can fully enable tracing across any commonly used 3rd party libraries without changing any code or rebuilding the project. The list of instrumented libraries is pretty comprehensive — Jersey, Cassandra drivers, MongoDB drivers to name but a few.

Project mention: Configurations for Anomaly Detection Kibana plugin | reddit.com/r/elasticsearch | 2021-06-14I'm trying to set up the anomaly detection for opendistro elasticsearch. On their official website, they have the documentation that explains how to set it up. https://opendistro.github.io/for-elasticsearch-docs/docs/ad/#get-started-with-anomaly-detection

So, you may be hitting SimpleFSDirectory instead, which does have issues with too many searches.
Could you share the reasons, MMapDirectory did not work for you?
