Configuration Example

  <application config="com.searchtechnologies.aspire:app-publish-to-gsa">

Note: Any optional properties can be removed from the configuration to use the default value described on the table above.

Edit Groovy

The default Groovy transformation file can be found in File:AspireToElasticsearchBulk.groovy.

The default transformation Groovy file provided by the publisher expects metadata as described in Connector AspireObject Metadata.

Add metadata field

To add a new metadata field extracted by an Aspire Connector add an groovy element inside the builder.$object() that is right after the builder.flush().

   metadata-name doc.metadatafield

Change the document ID

The id of a ElasticSearch document is used to uniquely identify a file in the index. By default, Publish To ElasticSearch will use the following fields from the Aspire document in order of precedence (if one is missing, then the next will be used):

  • fetchUrl
  • url
  • displayUrl
  • id

If you want to change this behavior, edit or create a new Groovy file which has the following element inside builder.index():

  '_id' value-for-id
