elasticsearchHow can I use the Elasticsearch DSL to build custom search queries?
The Elasticsearch DSL (Domain Specific Language) is a powerful query language for creating custom search queries. It provides a simple, powerful syntax for constructing complex queries.
Here is an example of a query using the Elasticsearch DSL:
GET /_search
{
"query": {
"match": {
"title": "Elasticsearch"
}
}
}
This query will return all documents that have the word "Elasticsearch" in the title
field.
The parts of the query are:
GET
- The HTTP method used to execute the query/_search
- The endpoint that is used to execute the queryquery
- The query clause that contains the search criteriamatch
- The type of query used to match documentstitle
- The field that is matched against the queryElasticsearch
- The query string that is used to match documents
For more information on the Elasticsearch DSL, please see the Elasticsearch documentation.
