# Querying
After scanning and enriching, you can explore your indexed files.
- [`ls`](ls.md) - List sources matching [filter expressions](../../reference/filter.md)
- [`facts`](facts.md) - Discover available facts and check coverage
- [`compare`](compare.md) - Compare directories to find overlap
All query commands support path scoping (limit to a subdirectory) and `--where` filters.
