Installing a Search Engine

Search engines are a critical component of your Liferay Portal installation. They allow you to provide documents in an index that can quickly be searched, rather than relying on expensive database queries.

If you’re here, you probably know the basics already and want to get started on configuring a search engine for your Liferay Portal deployment.
