Yes they are.
The walmart search engine has "specific" holidays (Hanukkah and Kwanzaa==even Ramadan gets specific answers).
But Christmas is in their "generic" category. To get to what you want to see you firsthave to pass through their Reeducation Page -- Holiday--then you can actually get to what you want.
The "specific" things that come up for Hanukkah and Kwanzaa are just the keyword search results. Christmas brings up a whole section and then you can move past that to just the keyword search results. Christmas is getting the extra treatment of getting a section and keyword while the others are just getting keyword.
