Method: Puppet::Node::Facts::DiffPuppetdb#search

Defined in:
lib/puppet/indirector/facts/diff_puppetdb.rb

#search(request) ⇒ Object

Search for nodes matching a set of fact constraints. The constraints are specified as a hash of the form:

‘=> value`

The only accepted ‘type` is ’facts’.

‘name` must be the fact name to query against.

‘operator` may be one of {eq, ne, lt, gt, le, ge, and will default to ’eq’ if unspecified.
