Search: compatibility with PostgreSQL

The search query used the comparison operator in a non-standard way, incompatible with PostgreSQL (HTTP error 500 in people/search). PostgreSQL does not do the implicit casting from integer to boolean, you must explicitly write TRUE/FALSE (recommended) or implement explicit casting (not ideal with frequent queries).
