To update or insert dynamic fields in Solr, you need to follow these steps:
- Ensure that the dynamic field definition is already present in your schema.xml file. Dynamic fields are defined using a wildcard (*) symbol, such as
- Use the Solr update endpoint to add, update, or delete documents in your Solr collection. You can perform these operations using HTTP requests, either manually or programmatically.
- When updating or inserting documents, make sure to include the dynamic fields in your JSON or XML document structure. For example, if you have a dynamic field named "*_s", you can add a field like "my_custom_field_s" to your document.
- Send the updated document to the Solr update endpoint, specifying the appropriate action (add, update, delete) and the document data. Solr will then process the request and update the collection accordingly.
- Verify that the dynamic fields are being correctly populated and indexed by querying the collection and checking the document fields. You can use the Solr admin interface or send a query request programmatically to confirm the changes.
By following these steps, you can successfully update or insert dynamic fields in Solr and ensure that your documents are properly indexed and searchable.

What is the role of dynamic field types in Solr configuration?
Dynamic field types in Solr configuration allow for dynamic mapping of fields based on patterns in field names. This means that when a document is indexed with a field name that matches a defined pattern, it will automatically be assigned the corresponding field type.
This can be useful in situations where there are a large number of fields with similar characteristics, as dynamic field types can save time and effort in manually defining each field type. Additionally, dynamic field types can also be used to handle fields that are not known in advance, providing flexibility in the indexing process.
Overall, dynamic field types play a key role in simplifying configuration and improving efficiency in handling varying field types in Solr.
How to update and insert dynamic fields in Solr?
To update and insert dynamic fields in Solr, you can use the Solr API or Solr client libraries like SolrJ for Java. Here's a general guide on how to update and insert dynamic fields in Solr:
- Update a Document with a Dynamic Field:
- Use the Solr API or SolrJ to send an update request to Solr.
- In the update request, specify the document ID and the dynamic field you want to update, along with the new value.
- For example, if you have a dynamic field "dynamic_field_*" and you want to update the value for the field "dynamic_field_123" in a document with ID "1234", you can send an update request like this:
1 2 3 4 5 6 |
{ "id": "1234", "dynamic_field_123": { "set": "new_value" } } |
- Send this update request to Solr, and the document with ID "1234" will be updated with the new value for the dynamic field "dynamic_field_123".
- Insert a Document with Dynamic Fields:
- Similarly, you can use the Solr API or SolrJ to send an add document request to Solr.
- In the add document request, specify the document ID and include the dynamic fields with their respective values.
- For example, if you want to insert a new document with ID "5678" and dynamic fields "dynamic_field_456" and "dynamic_field_789", you can send an add document request like this:
1 2 3 4 5 |
{ "id": "5678", "dynamic_field_456": "value1", "dynamic_field_789": "value2" } |
- Send this add document request to Solr, and the new document with dynamic fields "dynamic_field_456" and "dynamic_field_789" will be inserted into the Solr index.
By following these steps, you can easily update and insert dynamic fields in Solr using the Solr API or Solr client libraries.
How to dynamically update field settings in Solr schema.xml?
To dynamically update field settings in Solr schema.xml, you will need to follow these steps:
- Access the Solr admin interface: Open a web browser and navigate to the Solr admin interface by entering the URL of your Solr server followed by "/solr" (e.g. http://localhost:8983/solr).
- Go to the Schema browser: In the Solr admin interface, click on the "Schema" link in the left sidebar to access the Schema browser.
- Find the field you want to update: Locate the field whose settings you want to update by scrolling through the list of fields in the Schema browser.
- Edit the field settings: Click on the field name to open the field settings page. Here, you can update various settings such as field type, indexing options, etc.
- Save the changes: After making the desired updates to the field settings, click on the "Submit" button to save the changes.
- Reload the Schema: Finally, click on the "Reload" button in the Schema browser to apply the changes to the schema.xml file and make them effective in the Solr index.
By following these steps, you can dynamically update field settings in Solr schema.xml without the need to manually edit the schema file.
