How to search all fields of an indexed entity in ElasticSeacrch using hibernateSearch 6

php editor Baicao introduces a method to use Hibernate Search 6 to search all fields of index entities in Elasticsearch. Hibernate Search 6 is a powerful full-text search engine that integrates seamlessly with Elasticsearch. By configuring and using Hibernate Search 6, you can easily index all fields of an entity into Elasticsearch and implement efficient full-text search capabilities. This article will give you details on how to configure and use Hibernate Search 6 to achieve this goal. Following the steps in this article, you will be able to quickly build a powerful full-text search engine and improve the search capabilities of your application.

Question content

I have the following method to search in elasticsearch using hibernate search api. I am passing querystring value as "addresses.address_key:123" which is searched in addresses.address_key as mentioned in fields(addresses.address_key).

How to make this method accept any input in the query string, for example: first_name:john and make it search in all fulltextfields.

elasticsearch Version: 8.10 hibernatesearch version: 6.2.2

public page<employee> searchemployee(string querystring) {
       try {
            searchsession searchsession = search.session(entitymanager);

            searchresult<employee> searchresult = searchsession.search(employee.class)
                    .extension(elasticsearchextension.get())
                    .where(f -> f.simplequerystring().fields("addresses.address_key").matching(querystring))
                    .fetch(math.tointexact(page.getoffset()), page.getpagesize());

            page<employee> pageresult = new pageimpl<>(searchresult.hits(), page, searchresult.total().hitcount());
            return pageresult;
        } catch (searchexception pe) {
           throw pe;
        }
}

Indexed entity classes:

@Indexed(index = "employee")
public class Employee {

  @FullTextField(name = "employee_key")
  private String employeeKey;

  @FullTextField(name = "first_name")
  private String firstName;
    
  @IndexedEmbedded(includeEmbeddedObjectId = true, includeDepth = 2)
  private Address addresses;
}

public class Address {
    
  @FullTextField(name = "address_key")
  private String addressKey;

  @FullTextField(name = "street_name")
  private String streetName;

}

Workaround

You cantarget multiple fields explicitly when defining a predicate:

searchresult<employee> searchresult = searchsession.search(employee.class)
        .where(f -> f.simplequerystring()
                .fields("employee_key", "first_name", "addresses.address_key")
                .matching(querystring))
        .fetch(math.tointexact(page.getoffset()), page.getpagesize());

There is currently no option to target only "all text fields"; see https://www.php.cn/link/0b36451530d9491114523d4b66253837.

Also, to be clear, simple query string syntax does not support explicit reference to fields in the query string.

In this example:

f.simplequerystring().fields("addresses.address_key")
        .matching("addresses.address_key:123")

...The "addresses.address_key:" prefix ("addresses.address_key:123") in the search string has no specific meaning and will only be interpreted as the term found in the document.

You might as well write like this:

f.simplequerystring().fields("addresses.address_key")
        .matching("addresses.address_key 123")

But actually, I think what you want is this:

f.simpleQueryString().fields("addresses.address_key")
        .matching("123")
