Note that that searches the package descriptions. To search for
package names, add the -n option.

Temp file is unnecessary.

apt-cache search parted |awk '{print $1}'  |xargs dpkg -l  2>&1 | sed '1,/^+++/d'
un  parted                               <none>                         (no description available)
No packages found matching libparted1.8-10.
No packages found matching gparted.
No packages found matching fatresize.
No packages found matching gnu-fdisk.
No packages found matching libparted1.8-dbg.
No packages found matching libparted1.8-dev.
No packages found matching libparted1.8-i18n.
No packages found matching parted-doc.
No packages found matching qtparted.

Note that dpkg is not aware of all the packages returned by apt-cache
search, and prints a message on standard error for each one. Hence the
use of 2>&1 above.
