pg_search öneki neden beklediğim gibi çalışmıyor?

Question

Bu benim pg_search yöntemdir: docs recommend gibi tsearch için

pg_search_scope :node_search, against: [:name, :user_id, :circa, :cached_tagged_user_names, :cached_user_tag_list], 
    using: { tsearch: { any_word: true, dictionary: :english, prefix: true} }, 
    :associated_against => { 
     comments: [:message], 
     user: [:first_name, :last_name, :email], 
     memberships: [:relation], 
     user_tags: [:name] 
    } 

değil prefix: true. Bununla birlikte, en azından 1 özel durumda, beklediğim gibi çalışmıyor.

Şöyle bir Node nesne var. Aşağıdaki arama yaptığında

Bunun nedeni ne olabilir?

Ben önek arama dışına iten olabilir @ olduğunu düşünmüş, bu yüzden sadece dannyk@test.com için danny@test.com den cached_user_tag_list niteliğini değiştirerek test, işler daha garip yapmak için. Sonra dannyk için aradım ve doğru sonucu verdi, ancak danny için arama yaptığımda hala [] döndürür. Neden olduğuna dair hiçbir fikrim yok.

:trigram search'u açıp eşiği belirtebilirsiniz. Aranabilir metinde herhangi bir yerde görünen keyfi alt dizelerle eşleşir. Son kodunuz böyle görünürdü.

pg_search_scope :node_search, against: [:name, :user_id, :circa, :cached_tagged_user_names, :cached_user_tag_list], 
    using: { tsearch: { any_word: true, dictionary: :english, prefix: true}, :trigram => { :threshold => 0.1 } }, 
     :associated_against => { 
      comments: [:message], 
      user: [:first_name, :last_name, :email], 
      memberships: [:relation], 
      user_tags: [:name] 
     }
