I 'm assuming you 're using PHP with MySQL because of the reference to
$_REQUEST and using . To concatenate.

It could be a case, whitespace or data type issue.

Try using:

"SELECT
   *
FROM
   students
WHERE
   lower( trim( FName ) ) LIKE '% " . strtolower( trim(
$_REQUEST[ 'searchit '] ) ) . "% '
OR
   lower( trim( LName ) ) LIKE '% " . strtolower( trim(
$_REQUEST[ 'searchit '] ) ) . "% '
OR
   lower( trim( idStudent ) ) LIKE '% ". strtolower( trim(
$_REQUEST[ 'searchit '] ) ) . "% ' "

If your idStudent field is a numeric data type then you need to do an
equality comparision rather than a like...

"SELECT
   *
FROM
   students
WHERE
   lower( trim( FName ) ) LIKE '% " . strtolower( trim(
$_REQUEST[ 'searchit '] ) ) . "% '
OR
   lower( trim( LName ) ) LIKE '% " . strtolower( trim(
$_REQUEST[ 'searchit '] ) ) . "% '
OR
   idStudent = ". $_REQUEST[ 'searchit ']

If this doesn 't work please post the table structure (describe tablename)
and your PHP script.

Cheers

Dean
