A 1-character string has depth 1, but when its rank is reduced to 0, its depth is reduced as well. -In some cases nested array theory can remove a depth issue entirely, and not just partially. Most notable is the [search function result depth](../problems.md#search-function-depth) issue, in which it's impossible for a search function in BQN to return an atomic number because it always returns an array. Nested array theory doesn't have this issue since a scalar number is "just a number", and more complicated arrays can't cause problems because a search function's result is always a numeric array. The other half of the problem, about the non-principal argument depth, is only partly hidden, and causes problems for example when searching for a single string out of a list of strings. +In some cases nested array theory can remove a depth issue entirely, and not just partially.
