I`m wondering weather can I apply my formating specific function
before displaying all contents of already indexed collection. For
example: I want to display contents all in lowercase or in uppercase
just while displaying, which means stored collection remains as stored
before. Basically I want to run my javascript function like
document.toLowerCase(); while running document.dm; that allowing to
convert all collection text into lowercase. I looked document.dm, but
not understood.

Where should I add my JavaScript on this occasion?

Also I read approaches such as modifying CSS and GLI Format
Features-DocumentText[text].
But I want to run some Javascript, not want to add formating html tags
to [Text].

Could anyone help me?

Thank you in advance,
