我一直在研究一个 Grails 项目,与 ElasticSearch ( v 20.6 ) 结合,使用自定义构建的 elasticsearch-grails-plugin (以支持 geo_point 索引:v.20.6) 一直在尝试进行过滤搜索,同时使用 script_fields (计算距离)。以下是闭包和从 GXContentBuilder 生成的 JSON:
关闭
records = Domain.search(searchType:'dfs_query_and_fetch'){
query {
filtered = {
query = {
if(queryTxt){
query_string(query: queryTxt)
}else{
match_all {}
}
}
filter = {
geo_distance = {
distance = "${userDistance}km"
"location"{
lat = latlon[0]?:0.00
lon = latlon[1]?:0.00
}
}
}
}
}
script_fields = {
distance = {
script = "doc['location'].arcDistanceInKm($latlon)"
}
}
fields = ["_source"]
}
GXContentBuilder 生成的查询 JSON :
{
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"geo_distance": {
"distance": "5km",
"location": {
"lat": "37.752258",
"lon": "-121.949886"
}
}
}
}
},
"script_fields": {
"distance": {
"script": "doc['location'].arcDistanceInKm(37.752258, -121.949886)"
}
},
"fields": ["_source"]
}
使用 curl-way 的 JSON 查询工作得非常好。但是当我尝试从 Groovy 代码中执行它时,我的意思是这个(取自 ElasticSearchService.groovy),其中请求是 SearchRequest 实例:
elasticSearchHelper.withElasticSearch { Client client ->
def response = client.search(request).actionGet()
}
它抛出以下错误:
Failed to execute phase [dfs], total failure; shardFailures {[1][index][3]: SearchParseException[[index][3]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query_binary":"eyJxdWVyeSI6eyJmaWx0ZXJlZCI6eyJxdWVyeSI6eyJtYXRjaF9hbGwiOnt9fSwiZmlsdGVyIjp7Imdlb19kaXN0YW5jZSI6eyJkaXN0YW5jZSI6IjVrbSIsImNvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiI6eyJsYXQiOiIzNy43NTIyNTgiLCJsb24iOiItMTIxLjk0OTg4NiJ9fX19fSwic2NyaXB0X2ZpZWxkcyI6eyJkaXN0YW5jZSI6eyJzY3JpcHQiOiJkb2NbJ2NvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiddLmFyY0Rpc3RhbmNlSW5LbSgzNy43NTIyNTgsIC0xMjEuOTQ5ODg2KSJ9fSwiZmllbGRzIjpbIl9zb3VyY2UiXX0=","explain":true}]]]; nested: QueryParsingException[[index] No query registered for [query]]; }
如果我只使用上述闭包filtered = { ... } script_fields = { ... }
但它不返回计算出的距离,则上述闭包有效。
有人有类似的问题吗?
提前致谢 :)
有可能我在这里指出了明显的问题:P
