public class AllLowercasingSearcher extends LowercasingSearcher
Transform all terms in the incoming query tree and highlight terms to lower case. This searcher is a compatibility layer for customers needing to use FSAs created for pre-5.1 systems.

Add this searcher to your search chain before any searcher running case-dependent automata with only lowercased contents, query transformers assuming lowercased input etc. Refer to the Vespa documentation on search chains and search chain ordering.
