How can you combine to_tsvector results from two columns title and body in a query to create a single searchable document?

Ato_tsvector('english', title) || to_tsvector('english', body)

Bto_tsvector('english', title + body)

Cto_tsvector('english', title) + to_tsvector('english', body)

Dto_tsvector('english', title & body)

Step-by-Step Solution

Solution:

Step 1: Understand how to combine tsvector values and evaluate each option's method
PostgreSQL uses the || operator to concatenate tsvector values. to_tsvector('english', title) || to_tsvector('english', body) uses || correctly. to_tsvector('english', title + body) tries to add text before conversion, which is invalid. to_tsvector('english', title) + to_tsvector('english', body) uses + which is not valid for tsvector. to_tsvector('english', title & body) uses & which is invalid.
Final Answer:
to_tsvector('english', title) || to_tsvector('english', body) -> Option A
Quick Check:
Use || to combine tsvector results [OK]

Quick Trick: Use || to merge tsvector columns for search [OK]
