Sunspot-Solr Job Searcher Spike

So here is what I've come up with for the JobSearcher.

Brian suggested that breaking this out into another controller which is what I started doing. I haven't looked too much into what the convention here is, so this is just a spike.

I applied what I learned from looking at the Sunspot source to make the searcher.

The main property that we seem to organize Jobs into is by state. From there, an aspect can be called, returning a Sunspot object. I'm aware that some of this will become the responsibility of Tasks, but what I learned from looking at the Sunspot source can be applied to that as well.

Keyword Args and Hash-types

TLDR: keyword arguments only with with symbol-keyed hashes but DON'T symbolize keys on params unless you know what you're doing.

Ruby's keyword arguments only work with Hash objects where all of the keys are symbols.

They do not with:

ActionController::Parameters
ActiveSupport::HashWithIndifferentAccess

Cursor Pagination

It's my understanding that with cursor pagination, there are two types of cursor pagination that differ depending on what the cursor represents:

cursor represents a single point in the dataset
cursor represents a contiguous batch of the dataset

Cursor as Single Point

In this type, the cursor points to a specific point (maybe a record) in a dataset. This is the type used by Facebook and the response looks like this:

	module JobSearcher

	class << self

	def search(state: 'any_state', **params)
	searcher_class = "JobSearcher::#{ state.camelize }".safe_constantize
	if searcher_classes.include?(searcher_class)
	searcher_class.new(params)
	else
	nil
