# Description

`https://github.com/nushell/nushell/pull/7889#issuecomment-1407503567`
Make `search_terms` return empty string rather than nothing, so some
other command can handle it better
# User-Facing Changes
_(List of all changes that impact the user experience here. This helps
us keep track of breaking changes.)_
# Tests + Formatting
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
# After Submitting
If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
* Add input and output types to $nu.scope.commands
This commit changes the schema: instead of
command.signature: table
we now have
command.signatures: list<table>
with one signature for every input-output type pair.
* Represent signatures as a map from input_type to signature
* Sort signature entries
* Drop command name from signature tables
* Don't use "rest" as name of rest parameter; use empty string instead
* Bug fix: was creating records with repeated keys
E.g.
$nu.scope.commands | where name == 'hash sha256' | get signatures.0 | table -e
$nu.scope.commands | where name == 'transpose' | get signatures.0 | table -e
