Defined in:
lib/solrizer/extractor.rb

Overview

Provides utilities for extracting solr fields from a variety of objects and/or creating solr documents from a given object Note: These utilities are optional. You can implement .to_solr directly on your classes if you want to bypass using Extractors.

Each of the Solrizer implementations provides its own Extractor module that extends the behaviors of Solrizer::Extractor with methods specific to that implementation (ie. extract_tag, extract_rels_ext, xml_to_solr, html_to_solr)

#extract_hash(input_hash, solr_doc = Solr::Document.new) ⇒ Object

Populates a solr doc with values from a hash.

Accepts two forms of hashes:

> “t2”], ‘company’=>“c1”, “person”=>[“p1”, “p2”]

or

> => {‘technology’=>[“t1”, “t2”], ‘company’=>“c1”, “person”=>[“p1”, “p2”] }

Note that values for individual fields can be a single string or an array of strings.
