Re^3: Need something like a SQL query for JSON data structures (JSON::XS)

With a simple hash, to grep the keys:

my @results = grep /taco/, keys %hash;

To grep the values:

my @results = grep /taco/, values %hash;

To get the keys whose values match a regex:

my @results = map {$hash{$_} =~ /taco/ ? $_: ()} keys %hash;
