Plugins: Custom recursive queries?

Elastic Stack Elasticsearch
1

Hi there,

is it *generally *possible to extend the query capabilities with a plugin
in a way that recursive queries can be performed? Coarsly the plugin would
need to be able to do the following:

  1. Receive a parameterised custom JSON query and the starting values.
    (Custom DSL or custom REST endpoint possible via plugins?)
  2. Perform recursive queries (using current results as new values) until no
    further matches are found. (Querying via Java API?)

Cheers,

Jan

Yes, with plugins, you can generally register new client actions of all
kind. Assuming you mean cascading queries (queries that trigger other
queries) you can build it already on top of an ordinary search client, a
plugin is not required for that.

YMMV when it comes to reuse existing search code and features. For
example, right now, facets can not be customized via plugins, I hope for
this being added soon, it's scheduled after 0.90.
