Event Index - an LHCb Event Search System

Ustyuzhanin A., Artemov A., Kazeev N., Redkin A.

LHC experiments generate up to 10^11LHC experiments generate up to 1012 events per year. This paper describes Event Index – an event search system. Event Index’s primary function is quickly selecting subsets of events from a combination of conditions, such as the estimated decay channel or stripping lines output. Event Index is essentially Apache Lucene [1] optimized for read-only indexes distributed over independent shards on independent nodes. events per year.
