The database can be searched by using a combination of full text search terms and a selection of keywords and applies a top-down filtering approach. To start a search, just enter a search term and click on the Search-Button or click on any keyword in the Keywords-panel. If your search returns any results you can refine the search to limit the possible results further. To do this, you can modify your search terms or add/remove keywords by clicking on them either in the Keywords-panel or next to individual search results. As soon as your search has any result, the Keywords-panel will only display the currently selected keyword and keywords, dates and locations available for your current search results.
