Creating a data source lucene

        new LuceneX(new LuceneXConfig() {
            @Override
            public void configLuceneX(BaseConfig me) {
                me.add("d:/","test",Empty.class);
            }
        });

Defined entity classes

import com.ld.lucenex.field.FieldKey;
import com.ld.lucenex.field.LDType;

public class Empty{

    @FieldKey(type = LDType.IntPoint)
    private int id;
    @FieldKey(type = LDType.StringField)
    private String name;
    @FieldKey(type = LDType.TextField,highlight = true)
    private String text;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }
}

Add index

        List <Empty> = new new empties the ArrayList <> (10); 
        for (int I = 0; I <10; I ++) { 
            Empty Empty new new empty = (); 
            empty.setId (I); 
            empty.setName ( "News" ); 
            empty.setText ( "August 29, 2019 opening of the World Conference on artificial Intelligence in Shanghai, this General Assembly to" Zhaopin world, endless possibilities "as the theme, showing the latest national AI products and technologies, including China in this. session of the General Assembly, in addition to the latest AI technology and products on display various countries, AI chip wall Huawei, Cambrian, in accordance with plans and other domestic independent research and development of artificial intelligence chips even more attention by the visitors. the picture shows Microsoft brings intelligent recognition system dishes, put food on the cash register detection zone will be able to identify the price conscious, more powerful, the system also gives nutritional analysis reports, such as the content of calories, fat, carbohydrates, protein and so on. ") ; 
            empties.add (empty); 
        } 
        the ServiceImpl <empty> basisService = ServiceFactory.getService (ServiceImpl.class); 
        basisService.addObjects (empties);

Query Index

        ServiceImpl<Empty> basisService = ServiceFactory.getService(ServiceImpl.class);
        Empty searchOne = basisService.searchOne(new TermQuery(new Term("name","百度一下")));

    @FieldKey(type = LDType.TextField,highlight = true)
    private String text;

How to customize Service query interface

import com.ld.lucenex.service.ServiceImpl;

public class DemoService<T> extends ServiceImpl<T> {
    public DemoService(String sourceKey) {
        super(sourceKey);
    }
}
