How to get all solr field names except for multivalued fields?
问题
我是新手 solr，我试图查询字段名称，排除具有 multiValued=true 的字段。
到目前为止，我有
select?q=*:*&wt=csv&rows=0&facet
这会返回所有字段。
有没有一种方法可以修改查询以检查字段是否是多值的？
英文:
I'm new to solr and I'm trying to query for field names excluding fields with multiValued=true.
So far I have
select?q=*:*&wt=csv&rows=0&facet
which returns all the fields.
Is there a way to modify the query to check if a field is multivalued?

你可以通过Schema API获取有关所有已定义字段的信息。如果字段被定义为多值字段，响应将包含一个名为"multiValued"的字段，其值为true：
v1 API:
http://localhost:8983/techproducts/schema/fields
v2 API:
http://localhost:8983/api/collections/techproducts/schema/fields
{
"fields": [
{
"indexed": true,
"name": "_version_",
"stored": true,
"type": "long"
},
{
"indexed": true,
"multiValued": true, // 如果字段被定义为多值字段，则此处为true
"name": "cat",
"stored": true,
"type": "string"
},
],
"responseHeader": {
"QTime": 1,
"status": 0
}
}
英文:
You can retrieve information about all the defined fields through the Schema API. The response will contain a multiValued field set to true if the field is defined as multivalued:
v1 API:
http://localhost:8983/techproducts/schema/fields
v2 API:
http://localhost:8983/api/collections/techproducts/schema/fields
{
"fields": [
{
"indexed": true,
"name": "_version_",
"stored": true,
"type": "long"
},
{
"indexed": true,
"multiValued": true, <----
"name": "cat",
"stored": true,
"type": "string"
},
],
"responseHeader": {
"QTime": 1,
"status": 0
}
}
