You can also search against the specified data model or a dataset within that datamodel. Tags used with the Web event datasetsSplunk Enterprise creates a separate set of tsidx files for data model acceleration. They can be simple searches (root event datasets, all child datasets), complex searches (root search datasets), or transaction definitions. The indexed fields can be from indexed data or accelerated data models. CASE (error) will return only that specific case of the term.
