sift

I like sift tool which is best than most other grep tools, to search the huge log and code base.

sift also is easy customizations to default ignore case as below.

An example config file: ~/.sift.conf

{
      "BinarySkip": true,
      "Git": true,
      "GroupByFile": true,
      "IgnoreCase": true
  }
