Custom Trex Search Page for searching all documents

Hi,

Please help me to build a custom Trex search page. It should be like the Portal default's search page, an input box and a search button. But it should function differently.

It should return all documents on search whether released or unreleased.

I came to know from others' posts that if we give full control permission to 'index_service' user then it works for that particular folder.

But if I do that it affects the default seaqrch also.

Can we do it by coding, Any trex api available for returning all documents.

Please help

Regards
