Which of the following is the correct way to write a query using the @@ operator to search for the term 'database' in a tsvector column named content?

ASELECT * FROM articles WHERE content @@ 'database';

BSELECT * FROM articles WHERE content = to_tsquery('database');

CSELECT * FROM articles WHERE to_tsvector(content) @@ 'database';

DSELECT * FROM articles WHERE content @@ to_tsquery('database');

Step-by-Step Solution

Solution:

Step 1: Identify correct syntax
The @@ operator requires a tsvector on the left and a tsquery on the right.
Step 2: Check each option
SELECT * FROM articles WHERE content @@ to_tsquery('database'); correctly uses to_tsquery('database') as the right operand.
Final Answer:
SELECT * FROM articles WHERE content @@ to_tsquery('database'); -> Option D
Quick Check:
Use to_tsquery() on right side of @@ [OK]

Quick Trick: Left tsvector @@ right tsquery syntax [OK]

Common Mistakes:

Using '=' instead of @@
Passing plain text instead of tsquery on right side
Applying to_tsvector on left operand incorrectly
