Abstract: This document describes a search engine that accepts as input different types of data files and conditions for search parameters, including both single and multiple time points, concatenates these data, and outputs data from the different types of files that satisfies the specified search conditions. In one aspect, a method includes receiving a selection of a multiple input data files that each include data on which a search is to be performed. The input data files include different types of data files having different data formats. An in-memory data structure that includes the data of the input data files arranged in a common format is generated. For each of one or more search parameters, data indicating a condition for the search parameter is received. A set of data that satisfies the condition of each of the one or more search parameters is identified in the in-memory data structure.
