匹配所有查询
编辑匹配所有查询
编辑最简单的查询，它匹配所有文档，并为它们都赋予一个 _score 为 1.0。
$params = [
'body' => [
'query' => [
'match_all' => [
],
],
],
];
$response = $client->search($params);
resp = client.search(
query={
"match_all": {}
},
)
print(resp)
response = client.search(
body: {
query: {
match_all: {}
}
}
)
puts response
res, err := es.Search(
es.Search.WithBody(strings.NewReader(`{
"query": {
"match_all": {}
}
}`)),
es.Search.WithPretty(),
)
fmt.Println(res, err)
const response = await client.search({
query: {
match_all: {},
},
});
console.log(response);
GET /_search
{
"query": {
"match_all": {}
}
}
可以使用 boost 参数更改 _score。
resp = client.search(
query={
"match_all": {
"boost": 1.2
}
},
)
print(resp)
response = client.search(
body: {
query: {
match_all: {
boost: 1.2
}
}
}
)
puts response
res, err := es.Search(
es.Search.WithBody(strings.NewReader(`{
"query": {
"match_all": {
"boost": 1.2
}
}
}`)),
es.Search.WithPretty(),
)
fmt.Println(res, err)
const response = await client.search({
query: {
match_all: {
boost: 1.2,
},
},
});
console.log(response);
GET /_search
{
"query": {
"match_all": { "boost" : 1.2 }
}
}
匹配无查询
编辑这是 match_all 查询的反向查询，它不匹配任何文档。
resp = client.search(
query={
"match_none": {}
},
)
print(resp)
response = client.search(
body: {
query: {
match_none: {}
}
}
)
puts response
res, err := es.Search(
es.Search.WithBody(strings.NewReader(`{
"query": {
"match_none": {}
}
}`)),
es.Search.WithPretty(),
)
fmt.Println(res, err)
const response = await client.search({
query: {
match_none: {},
},
});
console.log(response);
GET /_search
{
"query": {
"match_none": {}
}
}
