Examples of org.apache.lucene.queries.TermsFilter$FieldAndTermEnum

org.apache.lucene.queries.TermsFilter
Constructs a filter for docs matching any of the terms added to this class. Unlike a RangeFilter this can be used for filtering on multiple terms that are not necessarily in a sequence. An example might be a collection of primary keys from a database query result or perhaps a choice of "category" labels picked by the end user. As a filter, this is much faster than the equivalent query (a BooleanQuery with many "should" TermQueries)

            // we use all non child types, cause we don't know if its exact or not...
            List<BytesRef> typesValues = new ArrayList<>(types.size());
            for (String type : context.mapperService().types()) {
                typesValues.add(Uid.createUidAsBytes(type, bValue));
            }
            return new TermsFilter(names.indexName(), typesValues);
        }
    }
