fpindexer is an FPC package that lets you create text indexes and search through them.
Plain text, HTML and Pascal input processors are included so you can create indexes out of those. You can write your own input text processors if needed. A database indexer is also provided so you can provide native Pascal full-text search for databases.
The indexes can be stored in sqlite, Firebird or in-memory (backed by flat file) databases.
