[sleuthkit-users] Question regarding keyword search

[Eagle I. S. <in...@ea...>]

I'm searching a drive for a keyword "Linda". 

It returns 143 hits, all listed like this::

438592 (Hex - Ascii)
offset 419 bytes

However, some of these show data and some do not. 
Example I could have another hit that has a size of 419 bytes
and when I click on the Ascii link, all I get is:

Error identifying block size (dcat -s output)

How can I see what's there?

Also, is there a way to enter multiple keywords in the search box?

TIA

Niall.
