Logical OR and First letter

Nico1904

Hello everyone,
First of all, thank for datatable, it's awesome !
I would like to use search by first letter and searching by first letter.
What I already did is that :
$( 'input', this.footer() ).on( 'keyup change clear', function () {
if ( that.search() !== this.value ) {
that
.search('\b'+this.value, true, false )
.draw();
}
} );

which allow me to search by first letter.
The problem is, if I want to use the logical OR (while adding |) the second item isn't searched by first letter.
I tried to split("|") and reconstruct my string in a loop and then search(string) but it doesn't work.
Do I do something wrong ?

You probably aren't building the correct regex expression. You can use regex101 to build the needed expression. I think you might need two backslashes in front of the b and your OR terms probably need to be in square brackets ([]). Something like this "\\b[a|b]".

If you still need help please build a test case so we can help debug your code.

Thank you for your answer.
There was two backslashes the first was ignored in the text.
It wasn't square brackets but parenthesis what I needed. Now it works thanks to your answer.
Final code :
$( 'input', this.footer() ).on( 'keyup change clear', function () {
if ( that.search() !== this.value ) {
that
.search('\\b('+this.value+')', true, false )
.draw();
}
} );
