Getting Started with Search

This guide provides instructions on initiating Search functionality within your application.

Suppose you wish to introduce a few entities to your application and enable searching across their attributes.

To begin, follow these steps:

  1. Include Search in your project following the guidelines in the installation section.

  2. Configure connection based on the service’s location.

Create Data Model and Views

Let’s create the classes listed below:

  1. The Status enumeration with the SILVER and GOLD values.

  2. The Customer entity with the fields:

    • firstName with String type

    • lastName with String type

    • status with Status type

    • card with FileRef type

  3. The Order entity with the fields:

    • date with Date type

    • number with String type

    • amount with Integer type

    • product with String type

    • customer with association to Customer, many-to-one cardinality

Set up the instance name for the Order entity to be displayed as the search result.

Create detail and list views for the Customer and Order entities.

Create Index Definition Interface

Next, it is necessary to establish an Index Definition - an interface outlining which entities and attributes are to be indexed. Suppose we intend to search orders based on their number, product name, customer status, or customer last name. Within the Index Definition, we will define a method to specify the required attributes.

@JmixEntitySearchIndex(entity = Order.class)
public interface OrderIndexDefinition {

    @AutoMappedField(includeProperties =
            {"number", "product", "customer.status", "customer.lastName"})
    void orderMapping();
}

  1. The interface should be annotated with @JmixEntitySearchIndex with the required parameter entity.

  2. The interface can be named arbitrarily.

  3. The @AutoMappedField annotation automatically maps requested properties. Here, we will utilize the includeProperties parameter to indicate the attributes to be indexed.

  4. The method can be named at your discretion.

Configure Index Naming

By default, index name is formed as <prefix><entity_name>. Default prefix is search_index_.

As you may utilize the same Elasticsearch/OpenSearch service across multiple projects, it is advisable to customize the default prefix for unique index names. To implement this change, add the following property to your application.properties file:

jmix.search.search-index-name-prefix = demo_prefix_

As alternative way you can specify full index name in indexName attribute of @JmixEntitySearchIndex.

Configure Indexing Queue Processing

The Jmix application monitors data modifications but does not automatically synchronize them with search engine service. To ensure regular updates of indexes, simply add the Quartz add-on to the project. The Search add-on will leverage Quartz for scheduled processing of the indexing queue using default configurations.

Create Search View

  1. Create an empty view named Search by utilizing the Blank view Studio template.

  2. Click Add Component in the actions panel, find the SearchField item, and then double-click it.

  3. The newly added searchField element will appear in both the Jmix UI structure panel and in the XML. You can configure attributes like id, height, width, etc., in the same way as it is done for other UI components.

    <search:searchField id="searchField"/>

Now, the view includes a text field for inputting the search term and a button to execute the search.

Test Searching in Application

Now, we are ready to launch and test the application.

Initially, add some instances of the Customer and Order entities.

Navigate to the Search view to locate customers with the Silver status.

The search outcomes will appear in the Search results view.

Clicking on a result will redirect you to the entity detail view.
