The search function within Obsidian is to search the NOTEs and the contents within the NOTEs(i.e. md files) based on the searching conditions.
By providing a searching term with keyword path:, one can get a searching result about the NOTE whose path fulfill the search condition. But not the content within the path.
If you want to navigate to the path, i.e. the folders, you may enable: Settings->Core plugins->File explorer.
p.s. for a starter, it is a good idea to check the core plugins. Those core plugins, maybe not all of them, I think are essential components for Obsidian.
Also, the Help Vault is good source for reading and https://help.obsidian.md has some information about some up-to-date new functions.
