elasticsearch ElasticSearch-用自定义评分替换评分系统
我正在使用以下设置和映射索引85000个文档:elasticsearch ElasticSearch-用自定义评分替换评分系统,elasticsearch,lucene,elasticsearch,Lucene,我正在使用以下设置和映射索引85000个文档: PUT /ap_dataset/ { "settings": { "index": { "store": { "type": "fs" }, "number_of_shards": 1, "number_of_replicas": 1 }, "analysis": { "analyzer": { "my_english": { "type": "english", "stopwords_
PUT /ap_dataset/
{
"settings": {
"index": {
"store": {
"type": "fs"
},
"number_of_shards": 1,
"number_of_replicas": 1
},
"analysis": {
"analyzer": {
"my_english": {
"type": "english",
"stopwords_path": "stoplist.txt"
}
}
}
}
}
PUT /ap_dataset/hw1/_mapping
{
"hw1": {
"properties": {

"type": "text",
"store": true,
"term_vector": "with_positions_offsets_payloads",
"analyzer": "my_english",
"fielddata": true
}
}
}
}
我使用的是ElasticSearch 5.4。我尝试以下列方式将默认评分替换为自定义评分:
GET /ap_dataset/document/_search
{
"query": {
"function_score": {
"query": {
"match": {
"text": "cow"
}
},
"boost_mode": "replace",
"functions": [
{
"script_score": {
"script": "_index['text']['cow'].tf()"
}
}
]
}
}
}
但我得到了以下错误:
{
"error": {
"root_cause": [
{
"type": "script_exception",
"reason": "compile error",
"script_stack": [
"_index['text']['fox'].tf( ...",
"^---- HERE"
],
"script": "_index['text']['fox'].tf()",
"lang": "painless"
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "ap_dataset",
"node": "zhCmVrZgRC-YQU5BOaz49w",
"reason": {
"type": "query_shard_exception",
"reason": "script_score: the script could not be loaded",
"index_uuid": "-TpUstdDQVSZnLwvLKWkPA",
"index": "ap_dataset",
"caused_by": {
"type": "script_exception",
"reason": "compile error",
"script_stack": [
"_index['text']['fox'].tf( ...",
"^---- HERE"
],
"script": "_index['text']['fox'].tf()",
"lang": "painless",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "Variable [_index] is not defined."
}
}
}
}
]
},
"status": 400
}
对这个问题有什么建议吗?
TIA这是一个编译错误。你确定_index是一些可访问的属性吗?这是5.4版本下的一个问题,从5.5版开始,他们将对访问_index字段发出警告。我设法用groovy脚本解决了这个问题。
