Description
CERN, the European Laboratory for Particle Physics, located in Geneva - Switzerland,
is currently building the LHC, a 27 km particle accelerator. The equipment life-cycle
management of this project is provided by the Engineering and Equipment Data
Management System (EDMS) Service. Using Oracle, it supports the management and
follow-up of different kinds of documentation through the whole life cycle of the LHC
project: design, manufacturing, installation, commissioning data etc...
The equipment data collection phase is now slowing down and the project is getting
closer to the “As-Built” phase; the phase of the project consuming and exploring the
large volumes of data stored since 1996.
Searching through millions of pieces of information (documents, pieces of equipment,
operations...) multiplied by dozens of points of view (operators, maintainers...)
require an efficient and flexible search engine. This paper describes the process
followed by the team to implement the search engine for LHC As-built project in the
EDMS Service. The emphasis is put on the design decision to decouple the search
engine from any user interface, potentially enabling other systems to also use it.
Projections, algorithms, and the planned implementation are described in this paper.
The implementation of the first version started in early 2007.
