First search query in Elasticsearch - Mini Project: Build & Apply

First search query

📖 Scenario: You have a small collection of books stored in Elasticsearch. You want to find books by their title.

🎯 Goal: Build a simple Elasticsearch query to find books with a specific word in their title.

📋 What You'll Learn

Create an index called books with sample book data

Set a search keyword variable called search_word

Write a query to find books where the title contains search_word

Print the titles of the matching books

💡 Why This Matters

🌍 Real World

Searching documents or records by keywords is a common task in many apps like libraries, stores, or websites.

💼 Career

Understanding how to build and run search queries is important for roles in data analysis, backend development, and search engine management.

1

Create the books index with sample data

Create a variable called books that holds a list of dictionaries. Each dictionary should have id and title keys with these exact entries: {'id': 1, 'title': 'The Great Gatsby'}, {'id': 2, 'title': 'Great Expectations'}, {'id': 3, 'title': 'The Grapes of Wrath'}.

Elasticsearch

# Create the books list with 3 dictionaries
# Your code here

Need a hint?

Use a list with dictionaries for each book.

2

Set the search keyword

Create a variable called search_word and set it to the string 'Great'.

Elasticsearch

books = [
    {'id': 1, 'title': 'The Great Gatsby'},
    {'id': 2, 'title': 'Great Expectations'},
    {'id': 3, 'title': 'The Grapes of Wrath'}
]
# Set the search_word variable
# Your code here

Need a hint?

Just assign the string 'Great' to search_word.

3

Write the search query logic

Create a list called results that contains all books from books where the search_word is found in the title. Use a list comprehension with book as the iterator variable.

Elasticsearch

books = [
    {'id': 1, 'title': 'The Great Gatsby'},
    {'id': 2, 'title': 'Great Expectations'},
    {'id': 3, 'title': 'The Grapes of Wrath'}
]
search_word = 'Great'
# Create results list with books containing search_word in title
# Your code here

Need a hint?

Use a list comprehension to filter books by title containing search_word.

4

Print the titles of matching books

Use a for loop with variable book to print the title of each book in results.

Elasticsearch

books = [
    {'id': 1, 'title': 'The Great Gatsby'},
    {'id': 2, 'title': 'Great Expectations'},
    {'id': 3, 'title': 'The Grapes of Wrath'}
]
search_word = 'Great'
results = [book for book in books if search_word in book['title']]
# Print the title of each book in results
# Your code here

Need a hint?

Use a for loop to print each matching book's title on its own line.
