Class CloneFieldUpdateProcessorFactory
java.lang.Object
org.apache.solr.update.processor.UpdateRequestProcessorFactory
org.apache.solr.update.processor.CloneFieldUpdateProcessorFactory
- All Implemented Interfaces:
- NamedListInitializedPlugin, SolrCoreAware
public class CloneFieldUpdateProcessorFactory
- extends UpdateRequestProcessorFactory
- implements SolrCoreAware
Clones the values found in any matching source field into
the configured dest field.
While the dest field must be a single <str>,
the source fields can be configured as either:
If the dest field already exists in the document, then the
values from the source fields will be added to it. The
"boost" value associated with the dest will not be changed,
and any boost specified on the source fields will be ignored.
(If the dest field did not exist prior to this processor, the
newly created dest field will have the default boost of 1.0)
In the example below, the category field will be cloned
into the category_s field, both the authors and
editors fields will be cloned into the contributors
field, and any field with a name ending in _price -- except for
list_price -- will be cloned into the all_prices
field.
