elasticsearchHow can I use the Elasticsearch API to perform a search?
You can use the Elasticsearch API to perform a search by using the _search
endpoint. For example, to perform a basic search using the GET
method, you can use the following code:
GET /_search
{
"query": {
"match_all": {}
}
}
This will return all documents in the index. You can also use more complex search queries to return more specific results. For example, to search for documents that contain the word elasticsearch
, you can use the following code:
GET /_search
{
"query": {
"match": {
"message": "elasticsearch"
}
}
}
This will return all documents that contain the word elasticsearch
.
