If I want to perform a search on an RPM package before installing it, how can this be done?

If I run yum info bind, it gives a basic overview:

[user@localhost ~]$ yum info bind

Available Packages

Summary      : The Berkeley Internet Name Domain (BIND) DNS (Domain Name System) server
URL          : https://www.isc.org/downloads/bind/
License      : MPLv2.0
Description  : BIND (Berkeley Internet Name Domain) is an implementation of the DNS
             : (Domain Name System) protocols. BIND includes a DNS server (named),
             : which resolves host names to IP addresses; a resolver library
             : (routines for applications to use when interfacing with DNS); and
             : tools for verifying that the DNS server is operating properly.

We can see which dependencies will be installed with yum install bind:

[user@localhost ~]$ sudo yum install bind

However, is there a way to query which dependencies and scripts will be installed via rpm? Example: rpm -q --scripts bind.x86_64 or rpm -ql bind.x86_64

[user@localhost ~]$ rpm -ql bind.x86_64
package bind.x86_64 is not installed

One could use yumdownloader to poke at the package:

# yum -y install yum-utils
# yumdownloader bind
# rpm -qp --scripts bind*.rpm

To avoid having to install yum-utils, another option might be:

# yum --downloadonly install bind
# find /var/cache/yum -name bind\*

This has the advantage of pulling down the dependencies, if you need to inspect those as well.
