v0.15.0 🚂

⚠️ Breaking changes

• Rename top-level module MeiliSearch to Meilisearch (#384) @ellnix
  We are now consistent with other usage of Meilisearch. Here is a convenient one-liner to move to the new spelling:

  find . -type f -exec sed -i 's/MeiliSearch/Meilisearch/g' {} \; 

  Using the old spelling is still functional, but will throw a warning for the time being.

🚀 Enhancements

• Support scopes in multi_search (#405) @ellnix
  You can now apply ActiveRecord scopes to multi_search:

  multi_search_results = Meilisearch::Rails.multi_search(
    # scope may be a relation
    'books' => { q: 'Harry', scope: Book.where("year < 2005") },
    # or a model
    'mangas' => { q: 'Attack', scope: Manga }
  )

  With this change, the :class_name option has been deprecated (since :scope achieves the same outcome), using it will cause a warning to be logged.
• Add federated search (#393) @ellnix
  This gem now supports federated search! Federated search is similar to multi-search, except the results are a single array sorted by ranking rules:

  results = Meilisearch::Rails.federated_search(
    queries: [
      { q: 'Harry', scope: Book.all },
      { q: 'Attack on Titan', scope: Manga.all }
    ]
  )

  <ul>
    <% results.each do |record| %>
      <li><%= record.title %></li>
    <% end %>
  </ul>
  
  
  <ul>
    <!-- Attack on Titan appears first even though it was specified second, 
         it's ranked higher because it's a closer match -->
    <li>Attack on Titan</li>
    <li>Harry Potter and the Philosopher's Stone</li>
    <li>Harry Potter and the Chamber of Secrets</li>
  </ul>

Thanks again to @ellnix! 🎉
