Full-text searches are currently implemented using wildcards; this approach is slow, although it may be faster than the Django version was. Full-text search should be made more efficient.

PostgreSQL's text search capabilities are likely to be sufficient. A separate full-text search engine like Elasticsearch is also a possibility.

Two challenges are anticipated:

• Integrating full-text search oriented toward natural languages with substring search. The latter is likely to be needed for many use cases, unless the full-text search engine can be configured to support it.
• Running appropriate queries using SQLAlchemy.
