When you turn on pruning, FST Builder will just remove nodes that don't have a high enough count of input terms traversing through them. E.g. if minSuffixCount1 is 100 then only FST nodes that see >= 100 input terms coming through them, are preserved.
You can use this to build a prefix trie instead of the full FST. Creating a custom tail freezer is very expert: it lets you implement arbitrary logic on which nodes are pruned or not.
