2011 Text Retrieval Conference  
In this paper we give a brief overview of the Webis group's participation in the TREC 2011 Sessions track with an extended version of our last year's approach [HSV10]. The basic idea can be described as a conservative query expansion based on terms used in previous queries or terms contained in clicked snippets. Furthermore, a query's result set is reduced by removing documents shown for previous queries or documents containing important terms from nonclicked snippets.
