使用Elasticsearch v7.0
这是我已实现的分析器(http://phoenyx2:9200/search_dev/_settings?pretty=true
):
{
"search_dev": {
"settings": {
"index": {
"refresh_interval": "30s",
"number_of_shards": "1",
"provided_name": "search_dev",
"creation_date": "1558444846417",
"analysis": {
"analyzer": {
"my_standard": {
"filter": [
"lowercase"
],
"char_filter": [
"my_char_filter"
],
"tokenizer": "standard"
}
},
"char_filter": {
"my_char_filter": {
"type": "mapping",
"mappings": [
"' => "
]
}
}
},
"number_of_replicas": "1",
"uuid": "hYz0ZlWFTDKearW1rpx8lw",
"version": {
"created": "7000099"
}
}
}
}
}
我已经重新创建了整个索引,但分析仍然没有变化。
我也运行了这个:url(phoenyx2:9200/search_dev/_analyze
)
{
"analyzer":"my_standard",
"field":"stakeholderName",
"text": "test't"
}
回复为:
{
"tokens": [
{
"token": "test't",
"start_offset": 0,
"end_offset": 6,
"type": "<ALPHANUM>",
"position": 0
}
]
}
我希望返回的令牌为“ testt
”

重新创建索引时,不足以在设置中定义新的分析器。
您还必须在映射中指定哪些字段使用哪个分析器,例如:
"mappings":{
"properties":{
"stakeholderName": {
"type":"text",
"analyzer":"my_analyzer",
},
}
}
您正在映射(可能)如下:
"mappings":{
"properties":{
"stakeholderName": {
"type":"text",
},
}
}
如果再次运行“分析”测试并删除该字段,则基本:
{
"analyzer":"my_standard",
"text": "test't"
}
您将获得:
{
"token": "testt",
"start_offset": 0,
"end_offset": 6,
"type": "<ALPHANUM>",
"position": 0
}
如您所料,坏消息哥们,但您必须再次重新索引所有数据,这一次在映射中指定要用于每个字段的分析器,否则弹性将默认为每个标准分析器时间。
