             Summary: geode example for lucene should add use case for nest 
object
                 Key: GEODE-9013
                 URL: https://issues.apache.org/jira/browse/GEODE-9013
             Project: Geode
          Issue Type: Bug
            Reporter: Xiaojian Zhou


We need to add example to guide users to use gfsh to insert nest object with 
array, then query on the array's item.

Here are the use case:

define following user object classes:
package examples;
  
import java.io.Serializable;

public class ExampleRegion implements Serializable {
  private ExampleIdentifier exampleIdentifier;
  public ExampleRegion() {}
  public ExampleRegion(ExampleIdentifier exampleIdentifier) {
    this.exampleIdentifier = exampleIdentifier;
  }
  public void setExampleIdentifier(ExampleIdentifier exampleIdentifier) {
    this.exampleIdentifier = exampleIdentifier;
  }
  public ExampleIdentifier getExampleIdentifier() {
    return this.exampleIdentifier;
  }
}

package examples;
  
import java.io.Serializable;

public class ExampleIdentifier implements Serializable {
  private String exampleId;
  private SystemId[] systemIds;
  public ExampleIdentifier() {}
  public ExampleIdentifier(String exampleId, SystemId[] systemIds) {
    this.exampleId = exampleId;
    this.systemIds = systemIds;
  }
  public void setExampleId(String exampleId) {
    this.exampleId = exampleId;
  }
  public void setSystemIds(SystemId[] systemIds) {
    this.systemIds = systemIds;
  }
  public String getExampleId() {
    return this.exampleId;
  }
  public SystemId[] getSystemIds() {
    return this.systemIds;
  }
}

package examples;

import java.io.Serializable;

public class SystemId implements Serializable {
  private String id;
  private String system;
  public SystemId() {}
  SystemId(String id, String system) {
    this.id = id;
    this.system = system;
  }
  public void setId(String id) {
    this.id = id;
  }
  public void setSystem(String system) {
    this.system = system;
  }
  public String getId() {
    return this.id;
  }
  public String getSystem() {
    return this.system;
  }
}

Then use gfsh to do insert and query:

gfsh>deploy 
--jar=/Users/gzhou/git3/lucene_example/build/libs/lucene_example-0.0.1.jar
gfsh>create lucene index --name=arrayIndex --region=/exampleRegion 
--field=exampleIdentifier.systemIds.system --analyzer=DEFAULT 
--serializer=org.apache.geode.cache.lucene.FlatFormatSerializer
gfsh>create region --name=exampleRegion --type=PARTITION
gfsh>put --region=/exampleRegion --key="('id':'1')" 
--value="('exampleIdentifier': {'exampleId': '000000000','systemIds':[{'id': 
'ID','system': 'MUREX'}]})" --value-class="examples.ExampleRegion"
gfsh>put --region=/exampleRegion --key="('id':'1')" 
--value="('exampleIdentifier': {'exampleId': '000000000','systemIds':[{'id': 
'Id','system': 'MUREX'}]})" --value-class="examples.ExampleRegion"
gfsh>put --region=/exampleRegion --key="('id':'2')" 
--value="('exampleIdentifier': {'exampleId': '000000001','systemIds':[{'id': 
'ID','system': 'MUREX'}, {'id': 'ID1','system': 'WHITEBOX'}]})" 
--value-class="examples.ExampleRegion"
gfsh>search lucene --name=arrayIndex --region=/exampleRegion 
--queryString="exampleIdentifier.systemIds.system:MUREX" 
--defaultField="exampleIdentifier.systemIds.system"
   key     |              value              | score
---------- | ------------------------------- | ----------
{'id':'1'} | examples.ExampleRegion@105ea825 | 0.2876821
{'id':'2'} | examples.ExampleRegion@4a0c4c91 | 0.25811607
