elasticsearchHow can I use Elasticsearch to order my results?
Elasticsearch offers a powerful way to order search results. It can be used to sort results based on relevance, date, or any other field.
For example, to order results by relevance, you can use the following code:
GET /_search
{
"query": {
"match": {
"title": "elasticsearch"
}
},
"sort": [
{
"_score": {
"order": "desc"
}
}
]
}
The output of the above code will be sorted by relevance, with the most relevant results appearing first.
To order results by date, you can use the following code:
GET /_search
{
"query": {
"match": {
"title": "elasticsearch"
}
},
"sort": [
{
"date": {
"order": "desc"
}
}
]
}
The output of the above code will be sorted by date, with the most recent results appearing first.
