在一个典型的聚变研究现场，实验数据是使用存档技术存储的，这些技术将每次放电作为一组独立的数据进行处理。这些技术（例如MDSplus或HDF5）通常补充有数据库，该数据库聚合多个镜头的元数据，以允许对某些预定义的量进行有效查询。然而，研究人员通常需要从档案中提取信息，可能是许多镜头，这些信息在元数据存储中不可用，或者以其他方式索引以进行快速检索。为了满足这一需求，通用原子TokSys控制设计和分析套件中添加了一个名为TokSearch的新搜索工具。该工具提供了快速执行任意，并行查询的存档托卡马克射击数据（原始和分析）在大量的镜头的能力。TokSearch查询API借用了SQL的概念，用户可以选择用Matlab™或Python实现查询。
At a typical fusion research site, experimental data is stored using archive technologies that deal with each discharge as an independent set of data. These technologies (e.g. MDSplus or HDF5) are typically supplemented with a database that aggregates metadata for multiple shots to allow for efficient querying of certain predefined quantities. Often, however, a researcher will need to extract information from the archives, possibly for many shots, that is not available in the metadata store or otherwise indexed for quick retrieval. To address this need, a new search tool called TokSearch has been added to the General Atomics TokSys control design and analysis suite. This tool provides the ability to rapidly perform arbitrary, parallelized queries of archived tokamak shot data (both raw and analyzed) over large numbers of shots. The TokSearch query API borrows concepts from SQL, and users can choose to implement queries in either Matlab™ or Python.
