We are experiencing some inconsistency in search results between two different environments. Both environments have documents with the dutch words "Fysio" and "Fysiotherapie". In one environment a search for "Fysio" results into finding documents containing both words. On the other environment, "Fysio" only results into finding a few "Fysio" pages and no "Fysiotherapie". Is this a bug or is there some setting that I can check which enables finding documents on partial words?
