Hey guys, I am trying to use the function score but I am getting the following error: ElasticsearchIllegalArgumentException[No field found for [fsot] in mapping with types [tst]]; I have used function score before and it worked like a charm so I started digging what was wrong. I found out that it does not work with object type. Am I doing something wrong? What am I missing here? The following gist contains an example and the error I received. > Thanks in advance, Pablo Musa -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hello Pablo , Lucene ( the underlying library library on which ES is build upon) has only key value concept and it does not keep object level information. This means that on Lucene side , data would be stored as fsot.testObjects : ["test1" , "test2"] And there is not field names as fsot on lucene side. This means that you need to give the field name as fsot.testObjects rather than fsot.

It worked. Thank you very much. - copying the final code for future referece: POST test/tst/\_search { "query": { "function\_score": { "boost\_mode": "replace", "query": { "filtered": { "query": { "match\_all": {} }, "filter": { "exists": { "field": "fsot" } } } }, "functions": [ { "script\_score": { "script": "if ( doc.get('fsot.testobj') == null ) 0; else 1;" } } ] } } } On Monday, August 25, 2014 12:33:47 AM UTC-3, vineeth mohan wrote: > Hello Pablo , > > Lucene ( the underlying library library on which ES is build upon) has > only key value concept and it does not keep object level information. > This means that on Lucene side , data would be stored as > > fsot.testObjects : ["test1" , "test2"] > > And there is not field names as fsot on lucene side. > This means that you need to give the field name as fsot.testObjects rather > than fsot. > > Thanks > Vineeth > > On Mon, Aug 25, 2014 at 7:57 AM, Pablo Musa \<[pabli...@gmail.com](mailto:pabli...@gmail.com) > \\> wrote: > > > Hey guys, > > I am trying to use the function score but I am getting the following > > error: > > > > ElasticsearchIllegalArgumentException[No field found for [fsot] in > > mapping with types [tst]]; > > > > I have used function score before and it worked like a charm so I started > > digging what was wrong.
