我正在尝试对存储在ES中的某些日志运行分面查询。日志看起来像
{"severity": "informational","message_hash_value": "00016B15", "user-agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0.1", "host": "192.168.8.225", "version": "1.0", "user": "User_1@test.co", "created_timestamp": "2013-03-01T15:34:00", "message": "User viewed contents", "inserted_timestamp": "2013-03-01T15:34:00"}
我正在尝试运行的查询是
curl -XGET 'http://127.0.0.1:9200/logs-*/logs/_search'
-d {"from":0, "size":0,
"facets" : {
"user" : {
"terms" : {"field" : "user", "size" : 999999 } } } }
请注意,日志中的字段"user"
是电子邮件地址。现在的问题是我使用的terms-facet
搜索查询会返回用户字段中的术语列表,如下所示。
u'facets': {u'user': {u'_type': u'terms', u'total': 2004, u'terms': [{u'count': 1002,u'term': u'test.co'}, {u'count': 320, u'term': u'user_1'}, {u'count': 295,u'term': u'user_2'}
请注意,该列表包含term
{u'count': 1002,u'term': u'test.co'}
这是用户电子邮件地址的域名。为什么elasticsearch将域视为一个单独的术语?
运行查询以检查映射
curl -XGET 'http://127.0.0.1:9200/logs-*/_mapping?pretty=true'
为"user"
字段
"user" : {
"type" : "string"
},
答案 0 :(得分:2)
这是因为elasticsearch的默认全局分析器在索引时标记“@”(除了空格和标点符号之类的内容)。您可以告诉elasticsearch不要在此字段上运行分析器,但您必须重新索引所有数据。
创建新索引
curl -XPUT 'http://localhost:9200/logs-new'
在此新索引的映射中指定您不想分析“用户”字段
curl -XPUT 'http://localhost:9200/logs-new/logs/_mapping' -d '{
"logs" : {
"properties" : {
"user" : {
"type" : "string",
"index" : "not_analyzed"
}
}
}
}'
索引文件
curl -XPOST 'http://localhost:9200/logs-new/logs' -d '{
"created_timestamp": "2013-03-01T15:34:00",
"host": "192.168.8.225",
"inserted_timestamp": "2013-03-01T15:34:00",
"message": "User viewed contents",
"message_hash_value": "00016B15",
"severity": "informational",
"user": "User_1@test.co",
"user-agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0.1",
"version": "1.0"
}'
elasticsearch facet现在将显示整个电子邮件地址
curl -XGET 'http://localhost:9200/logs-new/logs/_search?pretty' -d '{
"from":0,
"size":0,
"facets" : {
"user" : {
"terms" : {
"field" : "user",
"size" : 999999
}
}
}
}'
结果:
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ ]
},
"facets" : {
"user" : {
"_type" : "terms",
"missing" : 0,
"total" : 1,
"other" : 0,
"terms" : [ {
"term" : "User_1@test.co",
"count" : 1
} ]
}
}
}
