Overview

Our search is powered by Algolia, using their free community plan. Algolia conveniently provides the jekyll-algolia gem at https://github.com/algolia/jekyll-algolia for a smooth integration with jekyll.

In _config.yml the algolia-jekyll gem is configured as follows:

algolia:
  application_id: XXX
  index_name:     XXX
  search_only_api_key: XXX
  nodes_to_index: 'p,code,table'

Of note is the last entry nodes_to_index that determines which HTML tags will be indexed.

There is an upper limit on how much information one such node, e.g. the content of a <code></code> block, may contain. In rare cases extra long <code> blocks may have to be broken up into several ones.

Updating the index

The jekyll-algolia gem makes updating the index a breeze. Simply change into the root directory and execute:

ALGOLIA_API_KEY='XXX' bundle exec jekyll algolia

Be aware, that updates to the index count towards the limit of free operations, so it is recommended to update once a month.
