我有JSON對象,用於作業具有按鍵調用技能並且是技能列表的JSON對象。例如使用django和mongoengine執行正則表達式查詢

{ 
    "_id" : ObjectId("552a42cd03462b0728feb180"), 
    "did" : "JB77FW6885MCCRGG30T", 
    "attributes" : { 
     "EducationRequired" : "Bachelor's Degree", 
     "ExperienceRequired" : "At least 3 year(s)", 
     "ExternalApplication" : "True", 
     "City" : "Houston", 
     "Company" : "IBM", 
     "DegreeRequired" : "4 Year Degree", 
     "Skills" : { 
      "Skill" : [ 
       "apache hadoop", 
       "etl", 
       "geographic information system", 
       "cloud computing", 
       "mongodb", 
       "nosql", 
       "linux", 
       "spark (programming language)", 
       "java (programming language)", 
       "python (programming language)", 
       "sql", 
       "machine learning", 
       "data management", 
       "data integration" 
      ] 
     } 
    } 

} 

{ 
    "_id" : ObjectId("552a42cd03462b0728feb180"), 
    "did" : "JB77FW6885MCCRGG30T", 
    "attributes" : { 
     "EducationRequired" : "Bachelor's Degree", 
     "ExperienceRequired" : "At least 5 year(s)", 
     "ExternalApplication" : "True", 
     "City" : "Boston", 
     "Company" : "Microsoft", 
     "DegreeRequired" : "4 Year Degree", 
     "Skills" : { 
      "Skill" : [ 
       "java (programming language)", 
       "python (programming language)", 
       "sql", 
       "machine learning", 
       "data management", 
       "data integration" 
      ] 
     } 
    } 

} 

我想有「SQL」或'Java的

的工作,我有以下呼叫

skills = ['java','sql'] 
jobs = Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : skills}}) 

這樣做的問題是,它不返回具有'java'的作業,因爲在數據庫中,技能列表具有'java(編程語言)'而不僅僅是'java'。爲了解決這個問題,我需要在查詢中添加一個正則表達式。所以我嘗試了以下但他們都沒有工作:

Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['$/.*java.*/']}}) #ignoring sql for now 
Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['sql',re.compile('$/.*java.*/', re.IGNORECASE)]}}) 
Job.objects(__raw__={'attributes.Skills.Skill' : {'$in' : ['sql',re.compile('/.*java.*/', re.IGNORECASE)]}}) 

任何想法,我應該做什麼?

爲什麼不直接看'java(編程語言)'?像'skills = ['java(編程語言)','sql']'? – BorrajaX

,因爲java平臺等數據中還有其他java(xxxxxx)實例。通常候選人都有Java技能,但職業生涯API有java(編程語言)等等。 – Amer
