(Re)indexing tool

[jazzido]

Implement a shell extension to force a reindex of the IndexSpecs defined in neo4j.properties as a shell extension, just like neo4j-shell-tools.

If elasticsearch_index.spec is defined as people:Person(first_name,last_name), places:Place(name), the tool would perform two queries which result will be in turn sent to ElasticSearch:

• MATCH (n:Person) RETURN n.first_name, n.last_name sent to index people
• MATCH (n:Place) RETURN n.name sent to index places.

Hi @jexp,

Is there any documentation on how to implement a shell command? I've inherited my class from AbstractApp —just like in neo4j-shell-tools— but can't get Neo4j to recognize my command:

[jexp]

You missed to add the service loader for shell apps in src/main/resources

see: https://github.com/jexp/neo4j-shell-tools/blob/2.2/src/main/resources/META-INF/services/org.neo4j.shell.App

Perfect, thanks.

Just for the record, this has been implemented in PR #8, from my fork of neo4j-elasticsearch
