FileStorage", but I am looking for a simple example to start with. I tried 
something as below, it may be giving some result but is it going okay? If 
any one may please see and correct if required?

I'm not a whoosh user myself, but if I were to guess:

The content argument should contain the contents of the file, not the 
variable name, e. g.:
import io
...
ENCODING = "ascii" # replace with actual encoding of the file
txt_file1 = io.open("/python27/whooshtext1.txt", encoding=ENCODING).read()
...
writer.add_document(
    title=u"First document", 
    path=os.path.join(u"indexdir", u"a"),
    content=txt_file1)

u"flood" is indeed not in the string u"txt_file2" nor the string 
u"txt_file1", so that's the expected number of matches.
