我有一个数组字段包含一个字符串列表:ie。:[“NY”,“CA”]
在搜索时,我有一个匹配数组中任何字符串的过滤器。
我想根据搜索字符串出现次数最多的文档对结果进行排序:“NY”
结果应包括: 文件1:[“CA”,“NY”,“NY”] 文件2:[“NY”,FL“] 文件3:[“NY”,CA“,”NY“,”NY“]
结果应该按此订购
用户3,用户1,用户2
这可能吗?如果是这样,怎么样?

这将通过标准的Lucene评分实现来实现。如果您只是在不指定订单的情况下搜索“NY”,它将按相关性进行排序,并将为文档指定最高相关性,其中所有其他条件相同。

对于那些好奇的人,我无法根据数组中出现的单词数量来提升。然而,我确实完成了以下所需的工作:
curl -X POST "http://localhost:9200/index/document/1" -d '{"id":1,"states_ties":["CA"],"state_abbreviation":"CA","worked_in_states":["CA"],"training_in_states":["CA"]}'
curl -X POST "http://localhost:9200/index/document/2" -d '{"id":2,"states_ties":["CA","NY"],"state_abbreviation":"FL","worked_in_states":["NY","CA"],"training_in_states":["NY","CA"]}'
curl -X POST "http://localhost:9200/index/document/3" -d '{"id":3,"states_ties":["CA","NY","FL"],"state_abbreviation":"NY","worked_in_states":["NY","CA"],"training_in_states":["NY","FL"]}'
curl -X GET 'http://localhost:9200/index/_search?per_page=10&pretty' -d '{
"query": {
"custom_filters_score": {
"query": {
"terms": {
"states_ties": [
"CA"
]
}
},
"filters": [
{
"filter": {
"term": {
"state_abbreviation": "CA"

"boost": 1.03

{

"worked_in_states": [
"CA"

}
},
"boost": 1.02
},
{
"filter": {
"terms": {
"training_in_states": [
"CA"
]
}
},
"boost": 1.01
}
],
"score_mode": "multiply"
}
},
"sort": [
{
"_score": "desc"
}
]
}'
results: id: score
