Combining Queries with Bool
Explore the `bool` query to combine multiple queries using `must`, `should`, `must_not`, and `filter` clauses for complex logic.
Combine Search Logic
Welcome to combining queries! Up until now, we've looked at single search conditions. But real-world searches often need multiple criteria.
Elasticsearch's bool query is your go-to for building complex search logic. It lets you combine several queries using AND, OR, and NOT conditions.
Anatomy of a Bool Query
A bool query acts like a container for other queries. It has four main clauses:
must: All queries inside must match (AND).should: At least one query inside should match (OR).must_not: Queries inside must NOT match (NOT).filter: Queries inside must match, but don't affect relevancy score.
We'll explore each one!
