Yakagadziriswa: tora runyorwa rwese zvinyorwa mu django-elasticsearch-dsl

Dambudziko guru nderekuti Elasticsearch haina nzira yekuzvarwa yekuwana rondedzero yezvinyorwa zvese mune yakapihwa index. Unogona kushandisa API yekutsvaga, asi izvi zvinongodzosera gwaro rimwe chete panguva.

Ndiri kushandisa django-elasticsearch-dsl uye ndinoda kuwana runyorwa rwese gwaro mune index. Ndingazviita sei?

A:

Unogona kushandisa Search chinhu kubva django_elasticsearch_dsl. Ndiyo subclass ye ElasticsearchDSL Tsvaga chinhu, saka iwe unogona kushandisa nzira dzese kubva ipapo zvakare. Zvinyorwa zveizvo zviri pano: https://elasticsearch-dsl.readthedocs.io/en/latest/search_dsl.html#the-search-object

Kuwana magwaro ese

<code>from django_elasticsearch_dsl import Search, Index

s = 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!) &lt;--- this is what you want! &lt;--- this is what you want! &lt;--- this is what you want! &lt;--- this is what you want! &lt;--- this is what you want! len(response) # number of total hits found by query (slow!) &lt;--- this is what you want! &lt;--- this is what you want! &lt;--- this is what you want! &lt;--- 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.'
