Searchkick: Synonyms: "Faraday::TimeoutError: Net::ReadTimeout" when loading CSV

[Lowryderch]

I have a CSV file (2.5MB) and I get an error when I want to reindex:

// console

[2] pry(main)> Thema.reindex
Faraday::TimeoutError: Net::ReadTimeout
from /usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/net/protocol.rb:158:in `rbuf_fill'

// thema.rb

  searchkick match: :word_start,
             searchable: [:titel, :einleitung],
             language: "german",
             suggest: [:titel, :einleitung],
             highlight: [:titel],
             misspellings: {edit_distance: 3},
             synonyms: -> { CSV.read('vendor/assets/csv/openthesaurus.csv') }

// openthesaurus.csv

I found a workaround

// initializers/searchkick.rb

if Rails.env.development?
  Searchkick.client =
    Elasticsearch::Client.new(
      url: '127.0.0.1:9200',
      transport_options: {request: {timeout: 200}}
    )
end

The default timeout was too short.

Is there a better way?

Having a large set of synonyms will significantly increase indexing time - no way around that. You can increase the timeout as you did - Searchkick.timeout = 200 - or decrease the batch_size.
