Can't sort on string types with more than one value per doc


(cgascon) #1

Hi,

I'm trying to sort documents based on a field named "sortableSubject" (not
analyzed, type string).

But even though it's not analyzed, it throws the following exception:

"ReduceSearchPhaseException: Failed to execute phase [fetch], [reduce] ;
shardFailures {[1][1][4]: QueryPhaseExecutionException[[1][4]:
query[+(body:body* |
subject:body*)],from[0],size[5000],sort[<custom:"sortableSubject":
org.elasticsearch.index.field.data.strings.StringFieldDataType$1@14637eb>!]:
Query Failed [Failed to execute main query]]; nested: IOException[Can't sort

Am I missing something ? Can't we sort documents on string of many words ?

Are you sure its not analyzed? (try a get mapping request)
Are there multiple values - e.g. an array of sortableSubject?

I have come across this in 0.17.0 as well, and its somewhat inconvenient for my purposes as well. I guess there is not yet a way to make a multi-token string field both analyzed and sortable? (I guess this would require a new 'sortable' field mapping option). I really like having cake, but I really like to eat it too :slight_smile:

There is with the multi field option, or are you pointing to something else?
