MySQL Boolean Mode Full-Text Search Exercise with Solution

Boolean Mode Full-Text Search

Write a MySQL query to perform a full-text search in boolean mode on the "Content" column for the term "SQL" including the "+" operator.

Solution:

-- Perform a full-text search in BOOLEAN MODE for articles that must include the term 'SQL'.

-- Select all columns from the Articles table where the Content column includes the term 'SQL'.
SELECT * 
-- Specify the table from which to retrieve the data.
FROM Articles

-- Use the MATCH...AGAINST clause with BOOLEAN MODE to perform a full-text search.
-- The '+' operator before 'SQL' ensures that the term 'SQL' must be present in the results.
WHERE MATCH(Content) AGAINST('+SQL' IN BOOLEAN MODE);

Explanation:

• Purpose of the Query:
• To ensure that only articles containing the term "SQL" are returned.
• Demonstrates how to use BOOLEAN MODE to enforce term inclusion.
• Key Components:
• +SQL : The plus sign indicates the term must be present.
• IN BOOLEAN MODE : Specifies that the search should use boolean logic.
• Real-World Application:
• Beneficial for search features where certain keywords are mandatory in the result set.

Notes:

• Boolean mode allows the use of operators for more refined searches.
• Verify that full-text indexes support BOOLEAN MODE.
