What is the difference between using '$("input[name='search']").val();' versus '$("header #search input[name='search']").val();', with both using the "header #search" selector?

Can anyone explain the distinction between using "header #search" and not using it, and what it actually means? I'm not sure if I've provided enough information for a clear answer.

Here are the two code examples:

$('input[name=\search\']').val();
vs

$('header #search input[name=\search\']').val();
I'm trying to comprehend the dissimilarity between these two code snippets.

For your information, the following code snippet:

$("input[name=myname]")
Selects all <input> elements that have a name attribute with a value of "myname".

The main difference between $('input[name=\'search\']').val(); and $('header #search input[name=\'search\']').val(); is that the first statement selects all elements with a name attribute of "search" whereas the second statement selects all elements with a name attribute of "search" that are descendants of an element with an ID of "search" within a
element. Basically, the first statement is more general and will select all elements with a name attribute of "search" on the page, while the second statement is more specific and will only select elements named "search" that are descendants of an element with an ID of "search" within a
element. In general, it's better to be as specific as possible when selecting elements with jQuery to avoid accidentally selecting the wrong elements. If you know that the input you want to select will always be inside a
element with an ID of "search", then using the second statement is safer and more efficient.
