elasticsearchHow do I construct an Elasticsearch query to match a specific value?
To construct an Elasticsearch query to match a specific value, you can use the match
query. This query takes a field and a value as its parameters and returns documents that match the specified value in the specified field.
For example, to match documents with the value foo
in the field bar
, you could use the following query:
GET /_search
{
"query": {
"match": {
"bar": "foo"
}
}
}
This query will return all documents that have the value foo
in the field bar
.
The parts of the query are as follows:
GET /_search
: This is the endpoint used to search for documents."query": {
: This indicates the start of the query."match": {
: This indicates that thematch
query is being used."bar": "foo"
: This specifies the field and value that should be matched.}
: This indicates the end of the query.
For more information, see the Elasticsearch documentation on the match query.
