（使用ES 6.7） 我有一个索引，并希望支持按类型搜索功能。为此，我想尝试使用完成提示器，但是在重新编制索引以更改映射的旧索引时遇到了麻烦。
这是旧的索引映射
{
"old-index": {
"mappings": {
"doc": {
"properties": {
"content": {
"type": "text"
},
"project": {
"type": "keyword"
},
"title": {
"type": "text"
},
"version": {
"type": "keyword"
}
}
}
}
}
}
这是新的测试索引映射
PUT test-completion
{
"mappings": {
"doc": {
"properties": {
"content": {
"type": "text",
"fields": {
"autocomplete": {
"type": "completion",
"contexts": [
{
"name": "project",
"type": "category",
"path": "project"
},
{
"name": "version",
"type": "category",
"path": "version"
}
]
}
}
},
"title": {
"type": "text"
},
"project": {
"type": "keyword"
},
"version": {
"type": "keyword"
}
}
}
}
}
这是重新索引查询
POST _reindex
{
"source": {
"index": "old-index"
},
"dest": {
"index": "test-completion"
}
}
这是不返回任何结果的查询
POST test-completion/_search
{
"suggest": {
"autocompletion_suggest": {
"prefix": "part of documentation",
"completion": {
"field": "content.autocomplete",
"fuzzy": {
"fuzziness": "AUTO"
},
"contexts": {
"project": "xyz-project",
"version": "abc-version"
}
}
}
}
}
如果前缀设置为a或b，则返回上下文之外的结果。
我在哪里做错了？
