This provides a user interface which allows you to search terms used within Parliament using multiple filters. Selecting this option will show you the first few records from the dataset and then allow you to select data from the dataset by filtering on any of the attributes for the attendance. You will then be able to download or display the data in the following formats: CSV (e.g. for use in Microsoft Excel), TTL, Text, XML, JSON or RDF (e.g. for developers).
Developers can build API calls using the explorer tool. Help for the APIs can be found at http://explore.data.parliament.uk/?learnmore=Lords Attendances
