英文:
Return all documents in elastic that have a specified property regardless of value
问题
我正在尝试使用REST API查询Elasticsearch，以返回所有包含特定属性名称“content_blake3”的文档。属性的值不重要，我只想要具有这个属性的文档。
我尝试使用以下方式使用must和must_not请求，但仍然没有得到我需要的结果。
GET index-doc/_search
{
"query": {
"bool": {
"must_not": {
"match": {
"content_blake3": ""
}
}
}
}
}
任何帮助都会很感激。

你正在寻找存在查询：https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html
GET index-doc/_search
{
"query": {
"bool": {
"filter": {
"exists":{
"field": "content_blake3"
}
}
}
}
}
英文:
you're looking for the exists query: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html
GET index-doc/_search
{
"query": {
"bool": {
"filter": {
"exists":{
"field": "content_blake3"
}
}
}
}
}
