Multi-match query in Elasticsearch - Mini Project: Build & Apply

Multi-match Query in Elasticsearch

📖 Scenario: You are building a search feature for an online bookstore. Users want to search for books by matching their search words against multiple fields like title, author, and description.

🎯 Goal: Create an Elasticsearch multi-match query that searches for the word "adventure" in the title, author, and description fields.

📋 What You'll Learn

Create a JSON object called query with a multi_match key

Set the query value inside multi_match to the exact string "adventure"

Set the fields inside multi_match to the exact list ["title", "author", "description"]

Print the complete JSON query object

💡 Why This Matters

🌍 Real World

Multi-match queries are used in search engines to find matches across several fields, improving search relevance for users.

💼 Career

Knowing how to build multi-match queries is essential for roles involving Elasticsearch, such as backend developers, data engineers, and search specialists.

1

Create the base JSON query object

Create a JSON object called query with a multi_match key that contains an empty object.

Elasticsearch

query = {
    "multi_match": {
        
    }
}
# Your code here

Need a hint?

Start by creating a dictionary named query with a key multi_match that holds an empty dictionary.

2

Add the search term to the multi_match query

Inside the multi_match object in query, add the key query with the exact value "adventure".

Elasticsearch

query = {
    "multi_match": {
        # Add the query key with value "adventure" here
    }
}

Need a hint?

Add the key query inside multi_match and set it to the string "adventure".

3

Add the fields list to search in

Inside the multi_match object in query, add the key fields with the exact list value ["title", "author", "description"].

Elasticsearch

query = {
    "multi_match": {
        "query": "adventure",
        # Add the fields key with the list ["title", "author", "description"] here
    }
}

Need a hint?

Add the key fields inside multi_match and set it to the list ["title", "author", "description"].

4

Print the complete query JSON

Write a print(query) statement to display the complete multi-match query JSON object.

Elasticsearch

query = {
    "multi_match": {
        "query": "adventure",
        "fields": ["title", "author", "description"]
    }
}
# Print the query object below

Need a hint?

Use print(query) to show the full JSON query object.
