Hi, I can't find informations related to query / features syntax updates between old ES versions and more recent ones. Since we're using search and percolator queries, I want to be sure we won't have any bad surprise after upgrade. Are there any informations on this subject ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
