Swift GRDB FTS5: Full-Text Search Made Easy

GRDB is a Swift library for working with SQLite databases, and FTS5 is a full-text search extension for SQLite. When used together, GRDB provides a convenient and efficient way to work with FTS5 in Swift.

With GRDB FTS5, you can easily create an FTS5 virtual table in your SQLite database, index your data, and perform full-text search queries. The library also provides support for ranking search results, highlighting search terms, and optimizing search performance.

To use GRDB FTS5, you first need to add it to your project using Swift Package Manager. Then, you can create an FTS5 virtual table by defining a table schema and specifying the FTS5 module:

try db.create(virtualTable: 'books', using: FTS5()) { t in
    t.column('title')
    t.column('author')
}

Once you have created the virtual table, you can insert your data and perform full-text search queries using the MATCH operator:

let rows = try Row.fetchAll(db, sql: '''
    SELECT * FROM books WHERE books MATCH 'Swift AND programming'
''')

Overall, GRDB FTS5 is a powerful tool for implementing full-text search capabilities in your Swift applications using SQLite.
