Project

Description: What does this project do and who does it serve?

Project Setup

How do I, as a developer, start working on the project?

  1. What dependencies does it have (where are they expressed) and how do I install them?
  2. How can I see the project working before I change anything?

Using synonyms in Elasticsearch

We create an index with:

  • two filters: synonyms_expand and synonyms_contract
  • two analyzers: synonyms_expand and synonyms_contract
  • three text fields:
    • text_1 uses the synonyms_expand analyzer at index and search time
    • text_2 uses the synonyms_expand analyzer at index time, but the standard analyzer at search time
    • text_3 uses the synonyms_contract analyzer at index and search time
