No mapping found for field in order to sort on in ElasticSearch
elasticsearch, mapping, sorting
Solution
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
Problem
Elasticsearch throws a `SearchParseException` while parsing query if there are some documents found not containing field used in sort criteria. SearchParseException: Parse Failure [No mapping found for [price] in order to sort on] How can I successfully search these documents, even if some are missing the `price` field?
