Combining Queries
Elasticsearch allows you to combine multiple queries using boolean logic to create more complex search criteria.
Bool Query
The bool query is used to combine multiple queries using boolean operators such as must, should, must_not, and filter.
GET /products/_search
{
"query": {
"bool": {
"must": [
{ "match": { "name": "iphone" } },
{ "term": { "category": "electronics" } }
]
}
}
}
In this example:
- We’re using a bool query to find documents where the name field contains “iphone” and the category field is “electronics“.
- Elasticsearch will return documents that satisfy both conditions.
