Vous sauriez s'il existe une option dans une Lucene Query de Grafana de passer une variable de majuscule à minuscule ou inversement ?

J'ai une variable Grafana que le user doit renseigner en majuscule mais qui doit être exploitée en minuscule dans des graphiques...

Continued thread

approximate kNN search:
* good estimate
* you can control speed vs precision through the num_candidates setting (basically overfetching on the approximation for getting very close to exact kNN)
* #lucene uses HNSW: think of it as highways, roads & streets 🛣️ 3/9

Zulia Search Engine: Another Lucene based distributed search engine, that is written in Java. Using MongoDB in cluster mode for metadata sharing/node management it seems. Seems to be tailored for a certain use-case due to not having a lot of analyzers exposed. Communicating via GRPC.

Did not spot anything regarding distributed error handling and documentation is relatively sparse.Lucene is here to stay and going nowhere. #search #java #lucene
