New Elasticsearch 8 Java API - Sort by

zxuz111 · August 3, 2022, 11:17pm

I am using the new Elasticsearch 8 Java client API to query data and sort by one field.

esClient.search(s -> {
                return s
                    .index("employee")
                    .query(q -> q
                        .match(t -> t
                            .field("first-name")
                            .query("Michael")
                        )
                    )
                    .size(1)
                    .sort(so -> so
                        .field(FieldSort.of(f -> f
                            .field("age")
                            .order(SortOrder.Desc))
                        ))
                    ;
            },
            Employee.class
        );

And I got the following exception:

If I remove the code for sort, the query is working well. The documentation for the new API is limited. Am I using the correct syntex?

Any help will be greatly appreciated.
Thanks

Hi @zxuz111

What is the version of the java client, the age field is what type?

zxuz111 · August 4, 2022, 3:42am

Hi @RabBit_BR
Thanks for you reply. I am using the new Elasticsearch Java client:

		<dependency>
			<groupId>co.elastic.clients</groupId>
			<artifactId>elasticsearch-java</artifactId>
			<version>**8.3.1**</version>
		</dependency>

Field "age" is text, value is something like "KG2". As per your question, I tried to sort by an Integer field, and it's working fine.
Is there anything I missed that is required to be able to sort by a text field?
Thanks,

In this part of the documentation you will be able to understand why your sorting by field of type "text" did not work, in these cases it is always good to use fields of type "keyword" for sort or aggregation.

@RabBit_BR Thank you so much! You saved my day. I changed

.field("age")

to

.field("age.keyword")

and it's working like a charm.
