Indexing clean and deduplicated data in Elasticsearch

Before you begin

  • The Elasticsearch cluster and Elasticsearch-head are started before executing the Job.

    For more information about Elasticsearch-head, which is a plugin for browsing an Elasticsearch cluster, see https://mobz.github.io/elasticsearch-head/.

Procedure

  1. Double-click the tMatchIndex component to open its Basic settings view and define its properties.
  2. In the Elasticsearch configuration area, enter the location of the cluster hosting the Elasticsearch system to be used in the Nodes field, for example:

    "localhost:9200"

  3. Enter the index to be created in Elasticsearch in the Index field, for example:

    education-agencies-chicago

  4. If you need to clean the Elasticsearch index specified in the Index field, select the Reset index check box.
  5. Enter the path to the local folder from where you want to retrieve the pairing model files in the Pairing model folder.
  6. Press F6 to save and execute the Job.

Results

tMatchIndex created the education-agencies-chicago index in Elasticsearch, populated it with the clean data and computed the best suffixes based on the blocking key values.

You can browse the index created by tMatchIndex using the plugin Elasticsearch-head.

You can now use the indexed data as a reference data set for the tMatchIndexPredict component.
