Hi, I'm looking to write a plugin/module for Elasticsearch that adds a custom scoring function. This can't be a simple script score function as it does some matrix calculations integrating with other stuff, so it really needs to be a plugin. As far as I can see, the right interface to implement for this is ScoreFunctionParser. The question is, all the built-in function parsers seem to be registered in FunctionScoreModule, which binds a ScoreFunctionParserMapper with a set of ScoreFunctionParser , so can I still add in my own ScoreFunctionParser in there through my custom module registering a new ScoreFunctionParser? Would this work? Am I roughly on the right track here? Thanks, Mauricio -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
