The most relevant concepts in this branch are listed, for instance "Mice" and "Zebrafish". The number of matching search results is given in brackets and is illustrated with a small bar chart. The bar indicates the fraction compared to the overall result set count. The wider the bar the more often it occurs in the search result. On the right side are the search results with the query field and summary on top. The search summary contains information about the current and overall number of search result. The individual search results are presented as a list. Each result has a title and a short text extract. In both keywords and terms are highlighted. The number in front of the title represents the original result position.
