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.-
