||
| ## Sample data | ||
|
|
||
| ### IndexData class | ||
|
|
||
| ```java | ||
| static class IndexData { | ||
| private String firstName; | ||
| private String lastName; | ||
|
|
||
| public IndexData(String firstName, String lastName) { | ||
| this.firstName = firstName; | ||
| this.lastName = lastName; | ||
| } | ||
|
|
||
| public String getFirstName() { | ||
| return firstName; | ||
| } | ||
|
|
||
| public void setFirstName(String firstName) { | ||
| this.firstName = firstName; | ||
| } | ||
|
|
||
| public String getLastName() { | ||
| return lastName; | ||
| } | ||
|
|
||
| public void setLastName(String lastName) { | ||
| this.lastName = lastName; | ||
| } | ||
|
|
||
| @Override | ||
| public String toString() { | ||
| return String.format("IndexData{first name='%s', last name='%s'}", firstName, lastName); | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| ## Create an index | ||
|
|
||
| ```java | ||
| String index = "sample-index"; | ||
| CreateIndexRequest createIndexRequest = new CreateIndexRequest.Builder().index(index).build(); | ||
| client.indices().create(createIndexRequest); | ||
| ``` | ||
|
|
||
| ## Index data | ||
|
|
||
| ```java | ||
| IndexData indexData = new IndexData("John", "Doe"); | ||
| IndexRequest<IndexData> indexRequest = new IndexRequest.Builder<IndexData>().index(index).id("1").document(indexData).build(); | ||
| client.index(indexRequest); | ||
|
|
||
| indexData = new IndexData("John", "Joe"); | ||
| indexRequest = new IndexRequest.Builder<IndexData>().index(index).id("2").document(indexData).build(); | ||
| client.index(indexRequest); | ||
| ``` | ||
|
|
||
| ## Search for the documents | ||
|
|
||
| ```java | ||
| SearchResponse<IndexData> searchResponse = client.search(s -> s.index(index), IndexData.class); | ||
| for (int i = 0; i < searchResponse.hits().hits().size(); i++) { | ||
| System.out.println(searchResponse.hits().hits().get(i).source()); | ||
| } | ||
| ``` | ||
|
|
||
| ## Search documents using a match query | ||
|
|
||
| ```java | ||
| SearchRequest searchRequest = new SearchRequest.Builder().query(q -> q.match(m -> m.field("firstName") | ||
| .query(FieldValue.of("John")))) | ||
| .build(); | ||
|
|
||
| SearchResponse<IndexData> searchResponse = client.search(searchRequest, IndexData.class); | ||
| for (int i = 0; i < searchResponse.hits().hits().size(); i++) { | ||
| System.out.println(searchResponse.hits().hits().get(i).source()); | ||
| } | ||
| ``` | ||
|
|
||
| ## Aggregations | ||
|
|
||
| ```java | ||
| SearchRequest searchRequest = new SearchRequest.Builder().query(q -> q.match(m -> m.field("firstName") | ||
| .query(FieldValue.of("John")))) | ||
| .aggregations("firstNames", new Aggregation.Builder().terms(t -> t.field("firstName.keyword")) | ||
| .build()) | ||
| .build(); | ||
|
|
||
| SearchResponse<IndexData> searchResponse = client.search(searchRequest, IndexData.class); | ||
| for (Map.Entry<String, Aggregate> entry : searchResponse.aggregations().entrySet()) { | ||
| System.out.println("Agg - " + entry.getKey()); | ||
| entry.getValue().sterms().buckets().array().forEach(b -> System.out.printf("%s : %d%n", b.key(), b.docCount())); | ||
| } | ||
| ``` | ||
|
|
||
| ## Delete the document | ||
|
|
||
| The following sample code deletes a document whose ID is 1. | ||
|
|
||
| ```java | ||
| client.delete(d -> d.index(index).id("1")); | ||
| ``` | ||
|
|
||
| ## Delete the index | ||
|
|
||
| ```java | ||
| DeleteIndexRequest deleteIndexRequest = new DeleteRequest.Builder().index(index).build(); | ||
| DeleteIndexResponse deleteIndexResponse = client.indices().delete(deleteIndexRequest); | ||
| ``` |
