pg_search उपसर्ग क्यों काम नहीं करता है?

Question

यह मेरा pg_search विधि है: tsearchdocs recommend तरह के लिए

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] 
    } 

नहीं prefix: true।

हालांकि, कम से कम 1 विशेष मामले में, यह मेरी अपेक्षा की तरह काम नहीं करता है।

=> [#<Node id: 85, name: "House Fire 2", family_tree_id: 57, user_id: 57, media_id: 228, media_type: "Video", created_at: "2015-05-15 00:20:26", updated_at: "2015-06-08 22:25:49", circa: nil, is_comment: nil, cached_votes_total: 0, cached_votes_score: 0, cached_votes_up: 0, cached_votes_down: 0, cached_weighted_score: 0, cached_weighted_total: 0, cached_weighted_average: 0.0, cached_user_tag_list: "danny@test.com, abc@test.com", cached_num_user_tags: 2, cached_tagged_user_names: ["Daniel Marty", "Marcamus Prime"]>] 

नोट विशेषता: cached_user_tag_list उस ईमेल पते शामिल हैं: danny@test.com

मैं एक Node उद्देश्य यह है कि इस तरह दिखता है।

फिर भी, जब मैं निम्नलिखित खोजें कर इन परिणामों मैं कर रहे हैं:

क्या इस का कारण हो सकता है?

चीजें अधिक अजीब बनाने के लिए, मैंने सोचा कि यह @ कि उपसर्ग खोज बंद फेंकने जा सकता था, इसलिए मैं बस dannyk@test.com करने के लिए danny@test.com से cached_user_tag_list की विशेषता को बदलने के द्वारा इसका परीक्षण किया। तब मैंने dannyk की खोज की और यह सही परिणाम लौटा, लेकिन जब मैंने danny की खोज की तो यह अभी भी [] लौटाता है। मुझे कोई जानकारी नहीं है की क्यों।

आप :trigram search चालू कर सकते हैं और थ्रेसहोल्ड निर्दिष्ट कर सकते हैं। यह मनमाने ढंग से उप-तारों से मेल खाता है जो खोजने योग्य पाठ में कहीं भी दिखाई देते हैं। आपका अंतिम कोड इस तरह दिखेगा।

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 => {
