When you press Create New World, the mod parses the text and, if it contains recognized keywords, opens a search screen. It scans seeds around your chosen center (spawn or origin), locates structures from placement math and samples biomes with a fast native library when available (with a pure-Java fallback). When a seed matches, the world is created with it. The red dot indicates the player's approximate spawn point (the player's spawn point is selected after the world has been generated):

Keywords are recognized in Russian and English, with many synonyms.
