Question

在elasticsearch-py docs中，我找不到注册映射的示例，该映射执行这些REST API docs所说的内容：

put mapping API允许为特定类型注册特定的映射定义。

$ curl -XPUT 'http://localhost:9200/twitter/tweet/_mapping' -d '
{
    "tweet" : {
        "properties" : {
            "message" : {"type" : "string", "store" : true }
        }
    }
}
'

Answer 1

对索引执行任何操作都涉及Indices API。 PUTing映射也是许多Indices API之一。可以在Python客户端文档的Indices下的API Documentation部分找到它们。

您需要this: put_mapping(*args, **kwargs)。

Answer 2

这是一个完整的例子：

from elasticsearch import Elasticsearch
def fMap(document_type):
    mapping={document_type:{\
             "properties":{\
             "a_field":{"type":"integer","store":"yes"},\
             "other_field": {"type":"string","index":"analyzed","store":"no"},\
             "title":{"type":"string","store":"yes","index": "analyzed","term_vector":"yes","similarity":"BM25"},\
             "content":{"type":"string","store":"yes","index":  "analyzed","term_vector": "yes","similarity":"BM25"}\
             }}}
    return mapping
def dSetting(nShards,nReplicas):
    dSetting={
    "settings":{"index":{"number_of_shards":nShards,"number_of_replicas":nReplicas}},\
    "analysis":{\
        "filter":{\
        "my_english":{"type":"english","stopwords_path":"english.txt"},\
        "english_stemmer":{"type":"stemmer","language":"english"}},\
        "analyzer":{"english":{"filter":["lowercase","my_english","english_stemmer"]}}}}
    return dSetting
def EsSetup(con,idx,docType,dset,mapping):
    con.indices.delete(index=idx,ignore=[400, 404])
    con.indices.create(index=idx,body=dset,ignore=400)
    con.indices.put_mapping(index=idx,doc_type=docType,body=mapping)

conEs=Elasticsearch([{'host':'localhost','port':9200,'timeout':180}])
dMap = fMap('docTypeName')
dSet = dSetting(8,1)
EsSetup(conEs,'idxName','docTypeName',dset,dMap)

使用python如何注册特定的映射定义？
