MySQL Query Expansion Full-Text Search with Solution

Full-Text Search Using Query Expansion

Write a MySQL query to perform a full-text search with query expansion on the "Content" column for the term "optimization".

Solution:

-- Search for 'optimization' using query expansion.

-- Select all columns from the Articles table where the Content column matches the term 'optimization' or related terms.
SELECT * 
-- Specify the table from which to retrieve the data.
FROM Articles

-- Use the MATCH...AGAINST clause with QUERY EXPANSION to perform a broader search.
-- QUERY EXPANSION first finds rows matching the term 'optimization', then searches for additional terms related to those results.
WHERE MATCH(Content) AGAINST('optimization' WITH QUERY EXPANSION); 

Explanation:

• Purpose of the Query:
• To expand the search by including related terms, improving result accuracy.
• Demonstrates the use of query expansion in full-text searches.
• Key Components:
• WITH QUERY EXPANSION : Instructs MySQL to use additional relevant terms for the search.
• Real-World Application:
• Enhances user experience by returning a broader set of relevant results in content-heavy applications.

Notes:

• Query expansion might increase result set size; use when broader matching is desired.
• Verify performance impacts with larger datasets.
