Configuration
Hint
See the Search Index documentation to get a more high-level understanding of the search index concept in the Oro application.
OroSearchBundle provides options that you can use to customize the search functionality.
System Configuration
All configuration data is placed in the configuration under the alias
oro_search. Let us look at the configuration example:
Description of parameters:
engine_dsn, default “orm” (converted to container parameter oro_search.engine) - specifies the search engine name used to perform search and indexation (see section Search Engine Configuration);
engine_parameters (converted to the container parameter oro_search.engine_parameters) - additional parameters of the search engine used for initialization (e.g., IP, port, credentials, etc.);
log_queries, default false (converted to container parameter oro_search.log_queries) - a flag that defines whether it is necessary to log search queries to the database;
item_container_template, default “@OroSearch/Datagrid/itemContainer.html.twig” (converted to container parameter oro_search.twig.item_container_template) - template used to render an entity row in search results;
entities_config (converted to container parameter oro_search.entities_config) - entity search configuration that can be used to override the default entity search configuration (see section Entity Configuration).
Configuration Merging
All configurations merge in the boot bundles order. The application collects configurations of all nodes with the same name and merges them into one configuration. Merging uses simple rules:
if the node value is scalar, the value will be replaced
if the node value is an array:
by default, the value will be replaced
for node ‘fields’, this array will be appended by values from the second configuration.
After this step, the application knows about all entity search configurations from the search.yml files and has only one configuration for each entity.
Example
Acme\Bundle\DemoBundle\Entity\Question:
alias: acme_demo_question # Alias for 'from' keyword in advanced search
route:
name: acme_demo_question_view # Route name to generate url link to the entity record
parameters: # Array with parameters for route
id: id
search_template: '@AcmeDemo/Question/searchResult.html.twig' # Template to use in search result page for this entity type
fields:
-
name: subject # Name of field in entity
target_type: text # Type of virtual search field. Supported target types:
target_fields:
- subject
-
name: description
target_type: text
target_fields:
- description
Acme\Bundle\DemoBundle\Entity\Question:
alias: acme_demo_question # Alias for 'from' keyword in advanced search
fields:
-
name: priority
relation_type: many-to-one # Indicate that this field is relation field to another table.
relation_fields: # Supported: one-to-one, many-to-many, one-to-many, many-to-one.
-
name: label # related entity field name to index
target_type: text # related entity field name type
target_fields: # target fields to store field index
- priorityLabel
Result:
Acme\Bundle\DemoBundle\Entity\Question:
alias: acme_demo_question # Alias for 'from' keyword in advanced search
route:
name: acme_demo_question_view # Route name to generate url link to the entity record
parameters: # Array with parameters for route
id: id
search_template: '@AcmeDemo/Question/searchResult.html.twig' # Template to use in search result page for this entity type
fields:
-
name: subject # Name of field in entity
target_type: text # Type of virtual search field. Supported target types:
target_fields:
- subject

target_type: text
target_fields:

-
name: priority
relation_type: many-to-one # Indicate that this field is relation field to another table.
relation_fields: # Supported: one-to-one, many-to-many, one-to-many, many-to-one.
-
name: label # related entity field name to index
target_type: text # related entity field name type
target_fields: # target fields to store field index
- priorityLabel
Entity Configuration
After inserting, updating, or deleting entity records, the search index must be updated. The search index consists of data from entities by mapping parameters. Entity search configuration maps fields to the virtual search fields in the search index.
Entity search configuration can be stored in the main config.yml file (in oro_search config section) or in the search.yml files in the config directory of the bundle.
Configuration is an array that contains info about the bundle name, entity name, and the array of fields. Fields array contains the array of field names and field types. Data from all text fields will be stored in the all_text virtual field. Additionally, all the fields will be stored in the fieldName virtual fields if the target_fields parameter is not set.
Example:
Acme\Bundle\DemoBundle\Entity\Question:
alias: acme_demo_question # Alias for 'from' keyword in advanced search
route:
name: acme_demo_question_view # Route name to generate url link to the entity record
parameters: # Array with parameters for route
id: id
search_template: '@AcmeDemo/Question/searchResult.html.twig' # Template to use in search result page for this entity type
fields:
-
name: subject # Name of field in entity
target_type: text # Type of virtual search field. Supported target types:
target_fields:
- subject
-
name: description
target_type: text
target_fields:
- description
-
name: priority
relation_type: many-to-one # Indicate that this field is relation field to another table.
relation_fields: # Supported: one-to-one, many-to-many, one-to-many, many-to-one.
-
name: label # related entity field name to index
target_type: text # related entity field name type
target_fields: # target fields to store field index

Search Engine Configuration
The search bundle provides the ability to use different search engines through the common interface.
The used search engine is defined in the configuration under the oro_search.engine key. To make the engine work, at least one bundle must have s file with the Resources/config/oro/search_engine/<engine_name>.yml name that contains the configuration of search engine services that will be added to a container services.
To make the engine work, two services must be defined in the engine configuration:
search service oro_search.search.engine must implement Oro\Bundle\SearchBundle\Engine\EngineInterface.
indexer service oro_search.search.engine.indexer must implement Oro\Bundle\SearchBundle\Engine\IndexerInterface.
To make implementation easier, there are abstract classes Oro\Bundle\SearchBundle\Engine\AbstractEngine and Oro\Bundle\SearchBundle\Engine\AbstractIndexer that provide useful functionality (such as logging, queuing, etc.).
Suppose the search engine requires additional parameters (credentials, index configuration, etc.). In that case, they can be passed through the configuration using the oro_search.engine_parameters key so these parameters can be injected into search services.
Also, engine configuration can override existing services to support some specific use cases of the search engine (e.g., ORM engine overrides index listener to support single flush).
Datagrid Configuration
The SearchBundle supplies a datasource that can be used interchangeably with the default ORM datasource. This datasource feeds pure search index data, bypassing the default DBMS, thus allowing pure index storage layer-driven datagrids to be built.
The following is an example of a DatagridBundle’s configuration entry in the Resources/config/oro/datagrids.yml file that builds a simple user
datagrid using search index data only:
acme-demo-search-question-grid:
source:
type: search

- text.subject

- acme_demo_question
