From now on search results in LibriSourcePlus are being grouped in clusters and facets (shown in a pane on the right hand side of the screen).
Clustering in LibriSourcePlus is performed by a text analysis engine, which assigns each record to one or more topics. In addition records can be filtered by predetermined facets: by publication date and according to the database they are found in.
Facets and clusters are always displayed in the QuickSearch views, but in Advanced Search only when the user views the Combined Results (and, so, not when the user looks up the results per separate database). Furthermore, the number of records shown per cluster or facet does not apply to the sum total of search results, but is being calculated each time records are being retrieved (30 at a time per database).
