org.elasticsearch.search.slice.SliceQuery

org.elasticsearch.search.slice.TermsSliceQuery

public final class TermsSliceQuery
extends SliceQuery

A SliceQuery that uses the terms dictionary of a field to do the slicing. NOTE: The cost of this filter is O(N*M) where N is the number of unique terms in the dictionary and M is the average number of documents per term. For each segment this filter enumerates the terms dictionary, computes the hash code for each term and fills a bit set with the documents of all terms whose hash code matches the predicate. NOTE: Documents with no value for that field are ignored.
