Enhance Full-Text Search with a Partial GIN Index

Create a Partial GIN Index for Full-Text Search

Write a PostgreSQL query to create a partial GIN index on the "document" column in the Documents table for rows where "published" is true.

Solution:

-- Create a partial GIN index on the "document" column for published documents.
CREATE INDEX idx_documents_document_gin ON Documents USING gin (document)
WHERE published = true;

Explanation:

• Purpose of the Query:
• To optimize full-text search queries by indexing only published documents.
• This exercise demonstrates creating a partial index to save space and improve performance.
• Key Components:
• USING gin designates the GIN index type.
• WHERE published = true limits the index to a subset of rows.
• Real-World Application:
• Ideal for content management systems where only published documents need to be searched.

Notes:

• Partial indexes reduce overhead by indexing only relevant rows.
• They are particularly effective when only a fraction of the table's data is frequently queried.
