我的數據庫包含一個大型號的集合。的酒店(約121,000)。對具有相同電話號碼的文檔進行分組
這是我收集的樣子:
{
"_id" : ObjectId("57bd5108f4733211b61217fa"),
"autoid" : 1,
"parentid" : "P01982.01982.110601173548.N2C5",
"companyname" : "Sheldan Holiday Home",
"latitude" : 34.169552,
"longitude" : 77.579315,
"state" : "JAMMU AND KASHMIR",
"city" : "LEH Ladakh",
"pincode" : 194101,
"phone_search" : "9419179870|253013",
"address" : "Sheldan Holiday Home|Changspa|Leh Ladakh-194101|LEH Ladakh|JAMMU AND KASHMIR",
"email" : "",
"website" : "",
"national_catidlineage_search" : "/10255012/|/10255031/|/10255037/|/10238369/|/10238380/|/10238373/",
"area" : "Leh Ladakh",
"data_city" : "Leh Ladakh"
}
每個文檔可以有1個或多個被分割的電話號碼「|」分隔符。
我必須將具有相同電話號碼的文檔編組在一起。
實時,我的意思是,當用戶打開特定的酒店在網絡界面上查看其詳細信息時,我應該能夠顯示所有按常用電話號碼分組的酒店。
分組時,如果一個酒店鏈接到另一個酒店並且該酒店鏈接到另一個酒店,則應將所有3個酒店分組在一起。
Example : Hotel A has phone numbers 1|2, B has phone numbers 3|4 and C has phone numbers 2|3, then A, B and C should be grouped together.
from pymongo import MongoClient
from pprint import pprint #Pretty print
import re #for regex
#import unicodedata
client = MongoClient()
cLen = 0
cLenAll = 0
flag = 0
countA = 0
countB = 0
list = []
allHotels = []
conContact = []
conId = []
hotelTotal = []
splitListAll = []
contactChk = []
#We'll be passing the value later as parameter via a function call
#hId = 37443;
regx = re.compile("^Vivanta", re.IGNORECASE)
#Connection
db = client.hotel
collection = db.hotelData
#Finding hotels wrt search input
for post in collection.find({"companyname":regx}):
list.append(post)
#Copying all hotels in a list
for post1 in collection.find():
allHotels.append(post1)
hotelIndex = 11 #Index of hotel selected from search result
conIndex = hotelIndex
x = list[hotelIndex]["companyname"] #Name of selected hotel
y = list[hotelIndex]["phone_search"] #Phone numbers of selected hotel
try:
splitList = y.split("|") #Splitting of phone numbers and storing in a list 'splitList'
except:
splitList = y
print "Contact details of",x,":"
#Printing all contacts...
for contact in splitList:
print contact
conContact.extend(contact)
cLen = cLen+1
print "No. of contacts in",x,"=",cLen
for i in allHotels:
yAll = allHotels[countA]["phone_search"]
try:
splitListAll.append(yAll.split("|"))
countA = countA+1
except:
splitListAll.append(yAll)
countA = countA + 1
# print splitListAll
#count = 0
#This block has errors
#Add code to stop when no new links occur and optimize the outer for loop
#for j in allHotels:
for contactAll in splitListAll:
if contactAll in conContact:
conContact.extend(contactAll)
# contactChk = contactAll
# if (set(conContact) & set(contactChk)):
# conContact = contactChk
# contactChk[:] = [] #drop contactChk list
conId = allHotels[countB]["autoid"]
countB = countB+1
print "Printing the list of connected hotels..."
for final in collection.find({"autoid":conId}):
print final
這是一個代碼,我用Python寫的。在這一個中,我嘗試在for循環中執行線性搜索。我現在收到了一些錯誤,但它應該在糾正後運行。
我需要一個優化版本,因爲班輪搜索的時間複雜性較差。
我對此很新穎,所以歡迎任何其他改進代碼的建議。
謝謝。
我沒有關於它的很多知識,但可以elasticsearch幫我解決這個問題呢? – Anubhav
