PostgreSQL - Full-Text Search

How can you combine a tsvector column with a trigram index to optimize full-text search queries?

ACreate only a B-tree index on the tsvector column

BCreate a GIN index on the tsvector column and a GIN trigram index on the text column

CCreate a trigram index on the tsvector column directly

DUse a hash index on the tsquery column

Step-by-Step Solution

Solution:

Step 1: Understand indexing for full-text search
GIN indexes are used for tsvector columns to speed up full-text search.
Step 2: Use trigram index for text similarity
Trigram indexes (using pg_trgm) are created on text columns to optimize similarity searches.
Step 3: Combine both indexes
Creating a GIN index on the tsvector and a GIN trigram index on the original text column optimizes different search types.
Final Answer:
Create a GIN index on the tsvector column and a GIN trigram index on the text column -> Option B
