mnoGoSearch for Windows can store ispell files either in SQL database or load ispell files from disk. To choose ispell mode use "IspellMode text" or "IspellMode db". Note that "db" mode works with supported SQL database only and does not work with built-in database. "text" mode is faster than "db" in search time, while "db" is faster than "text" in indexing. You may configure indexer to use "text" mode and search front-end to use "db" mode (after having properly imported the same ispell files) at the same time.
