Search Administration
In Control Panel → Configuration → Search there are three administrative UIs: Connections, Index Actions, and Field Mappings. Connections shows you the search engines your installation is connected to, Index Actions is an interface for reindexing, and Field Mappings display fields mapped from Liferay to your search index.
Connections
Information about the search engine connection(s) is displayed here. For example,
- Search Engine Vendor: Elasticsearch
- Client Version: 7.16.3
- Active Connections: 1
- Health: Green
- Connection ID: _REMOTE_
- Connection Type: Read/Write
- Cluster Name: LiferayElasticsearchCluster
- Nodes: 1
- Node Name: lr-es
- Node Version: 7.17.21
Index Actions
In Index Actions you can reindex Liferay’s data.
You can reindex at one of these levels:
Global: reindex all indexes and types, or all spell check dictionaries.
Individual Indexable Types: reindex an indexable type individually.
-
Open Global Menu → Control Panel → Search and click the Index Actions tab.
-
[Liferay DXP 2023.Q4+/Portal GA102+] Choose the Reindexing Mode.
In Liferay DXP 2023.Q4/Portal GA102+ and later, you can configure the mode of the reindex to avoid search downtime. To learn about the introduced Concurrent and Sync modes, see Reindexing Modes.
-
[Liferay 7.4] Use the Execution Scope tab to choose the instances to reindex.
Beginning in Liferay 7.4, you can limit the scope of the reindex actions to specific Virtual Instances.
-
[Liferay DXP 2023.Q4+/Portal GA102+] Click Execute in the dialog to confirm the reindex.
Workflow Metrics are reindexed via the application’s dedicated settings menu. In the Global Menu, click Metrics in the Applications → Workflow section, then open the Settings window (
). See Reindexing Workflow Metrics for more information.
Reindexing All Content
When you reindex all content, all search engine documents in the system and company indexes are dropped and recreated from the database. Elasticsearch’s log prints update_mapping messages:
In Liferay 7.4 U45+/GA45+ and Liferay DXP 7.3 U14+, Liferay’s log reports when the reindex starts and finishes for system and company indexes. For example,
For earlier updates and Liferay Portal 7.3, enable these logging configurations to see similar information:
| Logger Category | Level |
|---|---|
| com.liferay.portal.search.internal.background.task.ReindexStatusMessageSenderImpl | DEBUG |
| com.liferay.portal.search.internal.SearchEngineInitializer | INFO |
Reindexing Individual Types
When you reindex an individual type (e.g., com.liferay.account.model.AccountEntry), the index documents representing the entities are dropped and recreated from the database. Elasticsearch’s log prints an update_mapping message:
In Liferay 7.4 U45+/GA45+ and Liferay DXP 7.3 U14+, Liferay’s log reports when the reindex starts and finishes. For example,
Reindexing Spell Check Dictionaries
Reindex the spell check dictionaries every time you reindex all content. When you reindex the spell check dictionaries, the content of Liferay’s dictionary file for each language (e.g., com/liferay/portal/search/dependencies/spellchecker/en_US.txt) is reindexed for the system and company index. Elasticsearch’s log prints an update_mapping message:
In Liferay 7.4 U45+/GA45+ and Liferay DXP 7.3 U14+, Liferay’s log reports when the reindex starts and finishes. For example,
Field Mappings
The Field Mappings tab shows you all field mappings that are effective in the system, by index. Currently, you can view the mappings, copy them, zoom in or out, and view them with a dark theme.
