Hibernate Search空间分面查询先运行5次，然后仅返回第5个结果

Question

我有一个在不同地理位置出售的汽车的索引，我正在寻找所有不同的制造商，这些制造商提供了在特定位置和特定价格范围内可提供的汽车数量。

我已经编写了查询代码，该代码似乎对前5次尝试都非常有效，然后结果似乎“粘在”第5个查询的纬度，经度和半径上。 更改价格元素会更改结果，但只能更改第5个查询的位置和半径。

我不确定是否必须“刷新”任何内容，或者这是配置问题，但是奇怪的是，查询仅在5次尝试后就停止工作。 我感到困惑，无法找到在线复制的问题，因此将不胜感激任何帮助或见解。

这是查询...

private List<VehicleManufacturer> getManufacturers( double valuation , double latitude , double longitude, int radius  ) throws Exception {

    long startTIme = new Date().getTime() ;

    List<VehicleManufacturer> returnedManufacturers = new ArrayList<VehicleManufacturer> () ;

    FullTextEntityManager manufacturerFullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(em);     
    QueryBuilder manufacturerBuilder = manufacturerFullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity(AvailableVehicle.class).get() ;

    // CREATE SPATIAL AND TOP PRICE FULL TEXT QUERY
    org.apache.lucene.search.Query manufacturingSpatialQuery = manufacturerBuilder.spatial().within( radius , Unit.KM ).ofLatitude( latitude ).andLongitude( longitude ).createQuery();
    org.apache.lucene.search.Query manufacturingValuationRoof = NumericRangeQuery.newDoubleRange("valuation", 0d , valuation , true, true); 
    org.apache.lucene.search.Query manufacturingValuationAndSpatialQuery =  manufacturerBuilder.bool().must(manufacturingValuationRoof).must(manufacturingSpatialQuery).createQuery() ;         
    FullTextQuery manufacturingFullTextQuery = manufacturerFullTextEntityManager.createFullTextQuery(manufacturingValuationAndSpatialQuery,  AvailableVehicle.class);

    // FACET  REQUEST
    FacetingRequest manufacturingFacetingRequest = manufacturerBuilder.facet().name( "manufacturerFaceting"  ).onField("manufacturer").discrete().orderedBy( FacetSortOrder.FIELD_VALUE ).includeZeroCounts(false).createFacetingRequest(); 

    FacetManager facetManager = manufacturingFullTextQuery.getFacetManager();
    facetManager.enableFaceting(manufacturingFacetingRequest);       
    List<Facet> facets = facetManager.getFacets( "manufacturerFaceting" );

    for (Facet manuacturingFacet : facets) {
        VehicleManufacturer manufacturer = new VehicleManufacturer( manuacturingFacet.getValue() , manuacturingFacet.getCount() ) ;
        returnedManufacturers.add( manufacturer ) ;         
    }

    System.out.println( "MANUFACTURERS count: "  + returnedManufacturers.size() + "  time: " + ( new Date().getTime() - startTIme )  + "ms  latitude:" +  latitude + "  longitude: " + longitude  + "  radius: " + radius  ) ;

    return returnedManufacturers ;      
}

...这是节略的索引对象类...

@Entity
@Indexed( index="AvailableVehicle"  )
@Spatial(spatialMode = SpatialMode.RANGE )
@Table(name = "car_available_vehicle")
public class AvailableVehicle  implements Coordinates {

@Id     
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "ID" )
private int id ;

@OneToOne()
@JoinColumn( name="VEHICLE_ID" )
private Vehicle vehicle ;

@Facet()
@Column(name = "MANUFACTURER" )
@Field(index=Index.YES, analyze=Analyze.NO, store=Store.NO)
private String manufacturer ;

@Facet()
@Column(name = "MODEL" )
@Field(index=Index.YES, analyze=Analyze.NO, store=Store.NO)
private String model ;

@Column(name = "LONGITUDE" )    
private Double longitude ;

@Column(name = "LATITUDE" )     
private Double latitude ;

@Column(name = "PRICE" )
@Field(index=Index.YES, analyze=Analyze.NO, store=Store.NO)
@NumericField( forField="price" )
private double price ;

@Column(name = "VALUATION" )
@Field(index=Index.YES, analyze=Analyze.NO, store=Store.NO)
@NumericField( forField="valuation" )
private double valuation ;

..这是休眠的Maven依赖项...

Answer 1

只是一个猜测，但是您可能会遇到HSEARCH-2691 。 该错误已在Hibernate Search版本5.7.1.Final 。 也许您可以尝试该版本？
