Install this sdk from source code:

python setup.py install

Please refer to sample.py for general information

Here list some information about query

you have three methods to trigger a query

search class could be write as link expression, each clause is a method

client = OpensearchClientFactory.create_client("hangzhou", "external", "accessKeyId", "accessKey") search = Search(self.client)

1. simple way, you could search.query("default:'阿里巴巴'", "default:'阿里妈妈'").index_name(app_name) it means query=default:'阿里巴巴' AND default:'阿里妈妈'

2. combination complex query condition using Q search.query(Q(default="title"), Q(default="中文")|Q(default="title3")).rank("校长").index_name(app_name1, app_name2) Please notice index_name is essential, and it supports multi application name :)

   Q is support all operates:

    Q(1) | Q(2) => default:'1' OR default:'2'
    Q(1) & Q(2) => default:'1' AND default:'2'
    Q(a=1), Q(2) | Q(3) => a:'1' AND (default:'2' OR default:'3')
    Q(a=1) & Q(b=2) | Q(c=3) => a:'1' AND b:'2' OR c:'3'
    Q(a=1), ~Q(b=2) => a:'1' ANDNOT b:'2'
   

   if you want to add RANK, rank() method will help you, please refer to test_search.py

3. too complicated query string... you think class Q can not be used, query_raw() method will help you execute plain query string

use config() method, the parameter is refer to http://help.aliyun.com/document_detail/opensearch/api-reference/query-clause/config-clause.html

use filter() method, the filter conditional is a little like query clause, just use FQ to combine complex filter rule

use sort() method

use aggregate() method, if you have more than one group parameter, you could call this method multi times, each time add a group parameter. for more parameter information, please refer to http://help.aliyun.com/document_detail/opensearch/api-reference/query-clause/aggregate-clause.html

use distinct() method, please refer to http://help.aliyun.com/document_detail/opensearch/api-reference/query-clause/distinct-clause.html for parameter's usage

use kvpairs() method
