  This short paper deals with the combination and comparison of two data
sources: Search engine results and query suggestions for 16 terms related to
political candidates and parties. The data was collected before the federal
election in Germany in September 2017 for a period of two months. The rank
biased overlap (RBO) statistic is used to measure the similarity of the
top-weighted rankings. For each search term and for both the search results and
query auto-completions we study the stability of the rankings over time.
