Basic Multi-Index Search Example
Let’s start with a basic example of performing a multi-index search across two indices: products and users.
Scenario: Searching for Products and Users
GET /products,users/_search
{
"query": {
"multi_match": {
"query": "Elasticsearch",
"fields": ["name", "description"]
}
}
}
In this example:
- We use the _search endpoint with a comma-separated list of indices (products and users) to perform a multi-index search.
- The multi_match query searches for the term “Elasticsearch” in the name and description fields across both indices.
Elasticsearch Multi Index Search
In Elasticsearch, multi-index search refers to the capability of querying across multiple indices simultaneously. This feature is particularly useful when you have different types of data stored in separate indices and need to search across them in a single query. In this article, we’ll explore what multi-index search is, why it’s important, and how to use it effectively with practical examples.
