我正在使用Elassandra来搜索邮件,使用Cassandra来保存邮件,使用ElasticSearch来搜索那些邮件。
我的问题是,从ElasticSearch 6开始,我们不能在一个映射中使用多种类型。这是我的映射:
"mappings": {
"mail__mail": {
"discover" : ".*",
"properties": {
"mailfrom": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
},
"ngram": {
"type": "text",
"analyzer": "edge_ngram_analyzer",
"search_analyzer": "edge_ngram_search_analyzer"
}
}
},
"subject": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
},
"ngram": {
"type": "text",
"analyzer": "edge_ngram_analyzer",
"search_analyzer": "edge_ngram_search_analyzer"
}
}
},
"date" : {
"type" : "date"
},
"folderid" : {
"type" : "text"
}
}
},
"mail__account" : {
"discover" : ".*",
"properties": {
"userId" : {
"type" : "Integer"
}
}
}
}
如何使用ElasticSearch 6在多个cassandra表中搜索?
最佳答案
从ES6开始,您需要为每个索引映射1个表。
搜索多个索引:
