No mapping found for field in order to sort on in ElasticSearch

Question

Elasticsearch throws a SearchParseException while parsing query if there are some documents found not containing field used in sort criteria.

Answer 1

After digging more, I found the solution as given below. ignore_unmapped should be explicitly set to true in the sort clause.

"sort" : [
       { "rating": {"order" : "desc" , "ignore_unmapped" : true} },
       { "price": {"order" : "asc" , "missing" : "_last" , "ignore_unmapped" : true} }
]

For further information have a look at the Elasticsearch references for:

• missing values
• ignoring unmapped fields
