Question

I have this in my controller:

Konkurrencer.where("title LIKE ?", "%#{params[:q]}%").limit(4)

I think this query is case sensitive. It should not be case sensitive.

Answer 1

You can use ILIKE in the where instead:

Konkurrencer.where("title ILIKE ?", "%#{params[:q]}%").limit(4)

From doc:

The key word ILIKE can be used instead of LIKE to make the match
case-insensitive according to the active locale. This is not in the
SQL standard but is a PostgreSQL extension.
