每当我尝试使用组合运算符查询索引时,&#34; $或&#34;。

我创建的索引是针对字段&#34; properties.PageName&#34;,当我查询一个文档时它工作正常,但是当我尝试多个文档时,我会收到在开头引用的错误响应。
如果它有帮助,这是电话: 发布https://xyz.cloudant.com/db/_find
请求正文:
{
"selector": {
"$or": [
{ "properties.PageName": "A8" },
{ "properties.PageName": "M30" },
{ "properties.PageName": "AH30" }
]
},
"use-index": "pagename-index"
}
答案 0 :(得分:6)
要执行$or
查询,您需要创建text
(全文)索引,而不是json
索引。例如,我刚刚创建了以下索引:
{
"index": {
"fields": [
{"name": "properties.PageName", "type": "string"}
]
},
"type": "text"
}
然后我就可以执行以下查询:
{
"selector": {
"$or": [
{ "properties.PageName": "A8" },
{ "properties.PageName": "M30" },
{ "properties.PageName": "AH30" }
]
}
}
