Hey, you need to use one of the score functions mentioned in > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. So either script\_score, boost factor, random or one of the decay functions.. the error message is also telling you not to forget the query field inside of the function score. --Alex On Fri, Nov 22, 2013 at 9:31 AM, paul [avinashpaul85@gmail.com](mailto:avinashpaul85@gmail.com) wrote: > What should be defined inside the function , any example queries. could > not find one on Elasticsearch page.this throws a exception No query > registered for [function\_score]] > { > "query":{ > "function\_score":{ > "query":{ > "match":{ > "programs":"computer science" > } > }, > "functions":[ > { > "filter":{ > "range":{ > "tution":{ > "from":10000, > "to":20000 > } > } > }, > "FUNCTION":{ > "boost": "3" > } > } > ], > "score\_mode":"avg", > "boost\_mode":"avg" > } > } > } > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
