我做了一个非常简单的测试来弄清楚我的错误,但没找到它。我创建了两个索引,并且我试图在 ppa 索引中搜索与 ods 索引中的给定文档类似的文档(如此处的第二个示例{ {3}})。
这些是我的ppa索引的设置,映射和文档:
PUT /ppa
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0,
"analysis": {
"filter": {
"brazilian_stop": {
"type": "stop",
"stopwords": "_brazilian_"
},
"brazilian_stemmer": {
"type": "stemmer",
"language": "brazilian"
}
},
"analyzer": {
"brazilian": {
"tokenizer": "standard",
"filter": [
"lowercase",
"brazilian_stop",
"brazilian_stemmer"
]
}
}
}
}
}
PUT /ppa/_mapping/ppa
{"properties": {"descricao": {"type": "text", "analyzer": "brazilian"}}}
POST /_bulk
{"index":{"_index":"ppa","_type":"ppa"}}
{"descricao": "erradicar a pobreza"}
{"index":{"_index":"ppa","_type":"ppa"}}
{"descricao": "erradicar a pobreza"}
这些是ods索引的设置,映射和文档:
PUT /ods
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0,
"analysis": {
"filter": {
"brazilian_stop": {
"type": "stop",
"stopwords": "_brazilian_"
},
"brazilian_stemmer": {
"type": "stemmer",
"language": "brazilian"
}
},
"analyzer": {
"brazilian": {
"tokenizer": "standard",
"filter": [
"lowercase",
"brazilian_stop",
"brazilian_stemmer"
]
}
}
}
}
}
PUT /ods/_mapping/ods
{"properties": {"metaodsdescricao": {"type": "text", "analyzer": "brazilian"},"metaodsid": {"type": "integer"}}}
POST /_bulk
{"index":{"_index":"ods","_type":"ods", "_id" : "1" }}
{ "metaodsdescricao": "erradicar a pobreza","metaodsid": 1}
{"index":{"_index":"ods","_type":"ods", "_id" : "2" }}
{"metaodsdescricao": "crianças que vivem na pobreza", "metaodsid": 2}
现在,此搜索无效:
GET /ppa/ppa/_search
{
"query": {
"more_like_this" : {
"fields" : ["descricao"],
"like" : [
{
"_index" : "ods",
"_type" : "ods",
"_id" : "1"
}
],
"min_term_freq" : 1,
"min_doc_freq" : 1,
"max_query_terms" : 20
}
}
}
但是这个确实有效:
GET /ppa/ppa/_search
{
"query": {
"more_like_this" : {
"fields" : ["descricao"],
"like" : ["erradicar a pobreza"],
"min_term_freq" : 1,
"min_doc_freq" : 1,
"max_query_terms" : 20
}
}
}
发生了什么事? 请帮助我让它返回空的东西。
答案 0 :(得分:0)
"更像这样"当您索引大量数据时,查询工作正常。空结果可能是弹性指数中存在的文件很少的症状。
