The search service can find package by either name (apache), provides(webserver), absolute file names (/usr/bin/apache), binaries (gprof) or shared libraries (libXm.so.2) in standard path. It does not support multiple arguments yet...

The System and Arch are optional added filters, for example System could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system.

RPM resource perl-experimental

This pragma provides an easy and convenient way to enable or disable experimental features. Every version of perl has some number of features present but considered "experimental." For much of the life of Perl 5, this was only a designation found in the documentation. Starting in Perl v5.10.0, and more aggressively in v5.18.0, experimental features were placed behind pragmata used to enable the feature and disable associated warnings. The 'experimental' pragma exists to combine the required incantations into a single interface stable across releases of perl. For every experimental feature, this should enable the feature and silence warnings for the enclosing lexical scope: use experimental 'feature-name'; To disable the feature and, if applicable, re-enable any warnings, use: no experimental 'feature-name'; The supported features, documented further below, are: * * 'array_base' - allow the use of '$[' to change the starting index of '@array'. This is supported on all versions of perl. * * 'autoderef' - allow push, each, keys, and other built-ins on references. This was added in perl 5.14.0 and removed in perl 5.23.1. * * 'bitwise' - allow the new stringwise bit operators This was added in perl 5.22.0. * * 'const_attr' - allow the :const attribute on subs This was added in perl 5.22.0. * * 'lexical_topic' - allow the use of lexical '$_' via 'my $_'. This was added in perl 5.10.0 and removed in perl 5.23.4. * * 'lexical_subs' - allow the use of lexical subroutines. This was added in 5.18.0. * * 'postderef' - allow the use of postfix dereferencing expressions, including in interpolating strings This was added in perl 5.20.0. * * 're_strict' - enables strict mode in regular expressions This was added in perl 5.22.0. * * 'refaliasing' - allow aliasing via '\$x = \$y' This was added in perl 5.22.0. * * 'regex_sets' - allow extended bracketed character classes in regexps This was added in perl 5.18.0. * * 'signatures' - allow subroutine signatures (for named arguments) This was added in perl 5.20.0. * * 'smartmatch' - allow the use of '~~' This was added in perl 5.10.0, but it should be noted there are significant incompatibilities between 5.10.0 and 5.10.1. * * 'switch' - allow the use of '~~', given, and when This was added in perl 5.10.0. * * 'win32_perlio' - allows the use of the :win32 IO layer. This was added on perl 5.22.0.
