The goal of this work is to build an application for full-text indexing of PIM data (according to the JSR-75 specification) on a portable device. This application consists of two parts: 1) Client, which runs on the portable device, which supports Java 2 Micro Edition with the JSR-75 extension. This part creates inverted lists, sends them to the server and allows sending of search queries and displaying their results. 2) Server, which runs on the Java virtual machine on a personal computer. This part uses the search engine Egothor 2 to create a file index and search it. To cut the costs tied to the transmission of necessary information and to ensure security of transmissions, the communication between the client and the server will be compressed and encrypted. The subject of this work is primarily the study of the selected encryption and compression methods sufficient for the correct mplementation and the verification of the availability and stabilty of the existing J2ME platform API and the Egothor2 search engine. |
