Dhibaatada ugu weyn ayaa ah Elasticsearch ma laha hab asal ah oo lagu helo liiska dhammaan dukumentiyada ku jira tusmada la bixiyay. Waxaad isticmaali kartaa API raadinta, laakiin tani waxay soo celinaysaa hal dukumeenti markiiba.
Waxaan isticmaalayaa django-elasticsearch-dsl waxaanan rabaa inaan helo liiska dhammaan dukumeentiyada ku jira index. Sideen u samayn karaa taas?
A:
Waxaad isticmaali kartaa Search shay ka django_elasticsearch_dsl. Waa fasal hoose oo ka mid ah ElasticsearchDSL Raadi shayga, si aad sidoo kale halkaas uga isticmaali karto dhammaan hababka. Dukumiintiyada kuwaa halkan ayaa yaal: https://elasticsearch-dsl.readthedocs.io/en/latest/search_dsl.html#the-search-object
Helitaanka dhammaan dukumentiyada
<code>from django_elasticsearch_dsl import Search, Indexs = Search(index='blog')
.query('match', title='python')response = s.execute()
for hit in response: # iterate over hits from response object
print(hit) # print each hit as a dict (default)for hit in s: # iterate over hits from search query directly
print(hit) # print each hit as a dict (default)for hit in s[0:10]: # slice results to get only first 10 hits
print(hit) # print each hit as a dict (default)len(s) # number of total hits found by query (slow!) <--- this is what you want! <--- this is what you want! <--- this is what you want! <--- this is what you want! <--- this is what you want! len(response) # number of total hits found by query (slow!) <--- this is what you want! <--- this is what you want! <--- this is what you want! <--- this is what you want! list(s)[0] # first result as a Python dictionary list(response)[0] # first result as a Python dictionary response[0] # first result as an ElasticSearch Hit response[0].meta # metadata associated with the Hit response[0].meta.score # score associated with the Hit response[0].title # title field value list(response)[1]['title'] ## second result's 'title' field value<;/pre>;<;br />;>;br />;The above code will return all documents matching your query, but it will not return any fields other than _id and _type unless they are explicitly requested via source(). To retrieve more fields, use source():<;br />;from django_elasticsearch_dsl import Search, Index, F ;from elasticsearch_dsl import Q ;import json ;import pprint ;pp = pprint.PrettyPrinter();pprint = pp.pprint ;s = Search().query('match', title='python').source([ 'title', 'body' ]) ;for i in range((len(s))): pprint((json.loads((str)(s[i]).replace("'", """)))) ;## or simply do it like below :## [{'body': 'Python and Django go together like peanut butter and jelly.'
