Your Soul Search preferences show which filters the matcher reads today.
Tribes: add tribes to your match pool and choose one mode across them all, Prefer (tribe souls first, then everyone) or Only (strictly tribe members). Your free plan includes one tribe in the pool; combining several is part of paid plans. Age is applied for real, in both directions. Preferred Quests say what you would like to explore together. Language is always required and always mutual.
Gender and location can be recorded on the preferences screen, but the matcher does not use them today, and the screen says so plainly. The "Filters" count pill only counts filters that really apply.
