I am using lucene 9.12 for my project I want to do facet with facet criteria and time range query
I refer many sites and check many combinations but all won't help me on this. Anyone please suggest to achieve facet count with facet and time criteria.
Here I have attached my sample code
public void dotestSearch(IndexReader reader){
System.out.println("NewFacetingImpl:: dotestSearch");
try
{
FacetsConfig facetsConfig = new FacetsConfig();
IndexSearcher searcher = new IndexSearcher(reader);
Query timeRangeQuery = LongPoint.newRangeQuery("timestamp",startDate,endDate);
DrillDownQuery drillDownQuery = new DrillDownQuery(facetsConfig);
drillDownQuery.add("category", "electronics");
drillDownQuery.add("timestamp", timeRangeQuery);
System.out.println("facet Query:: "+drillDownQuery);
// Create a DefaultSortedSetDocValuesReaderState for the "category" facet
SortedSetDocValuesReaderState state = new DefaultSortedSetDocValuesReaderState(reader);
// Collect facets from the matching documents
FacetsCollector facetsCollector = new FacetsCollector();
FacetsCollector.search(searcher, drillDownQuery, 10, facetsCollector);
SortedSetDocValuesFacetCounts srcFacetCounts = new SortedSetDocValuesFacetCounts(state, facetsCollector);
// Get the facet results for the brand field
//Facets facets = new SortedSetDocValuesFacetCounts(state, facetsCollector);
FacetResult result = srcFacetCounts.getTopChildren(10, "brand");
System.out.println(" facet counts for dst facet");
if (result != null) {
for (LabelAndValue lv : result.labelValues) {
System.out.println(lv.label + ": " + lv.value);
}
} else {
System.out.println("No results found.");
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
thanks inadvance!
