The assisted search was applied according to Nazemi et al. [19] and extends the search functionalities beside traditional linguistic methods with a topic-based approach. The approach incorporates the information of the generated topics to enhance search-terms from the query. The topics provide N-Grams, which are the most used phrases within each topic. These phrases often represent different ways to articulate the idea of the topic and consequently can be used as a key phrase to represent the topic. We use data from the phrases and choose the top five most used phrases as additional search-terms to extend the result set. Based on the initial users’ search the most dominant topic in the result set is identified. In the next step, semantically similar phrases are extracted based on the identified dominant topic. Additional searches are performed by the system using the semantically similar phrases as search-terms. The functionality can be activated with one click on top next to the search field. The advanced search is detecting automatically all data rows in the database and provides dedicated search in those tables.
