Architecture
Application architecture consist of three main parts. Core part of application is SAP HANA XS application that stores store and index content of collected files. XS application is providing HTTP services that allows external File indexing agents to register upload files and their contents. File indexing agent is reading and parsing text files into smaller chunks that represent separate events or logs that was written into file. These chunks then agent uploads to XS application through HTTP interface. Last part is actual user interface application based on HTML5 and SAPUI5 library. Web application is using services of XS application for searching through uploaded file contents.

or pressing ENTER on keyboard.

Additional filters
Sometimes user wants to pick certain file location or file itself, where the search engine will look for key word.
Mentioned properties can be filtered by using patterns. If you for example chose Origin and type 'DVD' to input field Pattern it will find all Origins that contains 'DVD'.
Result distribution chart
Once user gets search results distribution column chart shows, what is a distribution of results per particular day. Chart displays only days where at least 1 result was found for specified date range.
Results
Based on filter settings, results are displayed in form of table with mentioned columns in chronological order (ascending).
If search contains more than 20 results, table will show only first 20 entries. If it is necessary to show more records, user can click on 'More' option that loads another 20 rows. This option is visible in the end of table.
