Content Indexing Flow
How does content get indexed in Elastic Search
â
- 1.Content create, update, publish, retire etc APIs are called and content is updated in Neo4j
- 2.Neo4j writes these updates to a log file, typically located at
/data/logs/learning_graph_event_neo4j.log. This file needs to have the right permissions i.e. it needs to be owned by the user neo4j is running as. Usually this islearning - 3.The logstash service picks up lines from this log and pushes as events into the dev.learning.graph.events topic
- 4.The search indexer service picks up events from above topic and creates/updates the records in ES
- 5.The search indexer config affects how the data is inserted
- 1.nested.fields affects how certain fields are mapped
- 2.restrict.objectTypes - Any records with these object types is not inserted into ES
- 6.This applies to all the object types stored in Neo4J - Content, Collection, Question, QuestionSet, License, Framework, Channel
