Hi All,
i am trying to add Termfilter and DistanceFilter in BooleanFilter using
FilterClause. But i am getting the below mentioned error. Please check my
code and guide me.
*Code:*
> DistanceQueryBuilder queryBuilder = new DistanceQueryBuilder(latLong[0],
> latLong[1], radius, "lat", "lon", CartesianTierPlotter.DEFALT_FIELD_PREFIX,
> true);
> DistanceFieldComparatorSource distComp = new
> DistanceFieldComparatorSource(queryBuilder.getDistanceFilter());
> Sort distSort = new Sort(new SortField("", distComp,true));
> QueryParser parser = new QueryParser(Version.LUCENE_30, "city",
> new StandardAnalyzer(Version.LUCENE_30));
> Query query = parser.parse(strQuery);
> System.out.println(" distance sort details ::: "+ distSort);
> BooleanFilter boolFilter = new BooleanFilter();
> FilterClause filterClause2 = new
> FilterClause(queryBuilder.getFilter(), BooleanClause.Occur.MUST);
> boolFilter.add(filterClause2);
>
> Term term = new Term("city", "chengalpat");
> TermsFilter filter = new TermsFilter();
> filter.addTerm(term);
> FilterClause filterClause = new FilterClause(filter,
> BooleanClause.Occur.SHOULD);
> boolFilter.add(filterClause);
>
> TopDocs topDocs = searcher.search(query,boolFilter, 20,distSort);
