But the small difference is crucial.

When waisindex runs, it looks at the fmt file.  And if the fmt file
says to use soundex, it converts each word into its soundex code and
enters the soundex codes into the inverted index (the *.inv file).

So, when you use waissearch, it should also look at the fmt file, and
if the query searches in a field which was indexed using soundex, the
search term should also be converted into the soundex code, and then
waissearch should look for the soundex code in the index.

So, let's say the word is `Miller'.  When indexing, waisindex turns it
into the soundex code (M320, say), and puts that into the *.inv file.
And when you then search for Miller, waissearch converts that into
M320 and looks in the index for M320.

Different, but similar-sounding, words get the same soundex code.  For
example, Smith and Smithee and Smythe will get the same soundex code.
This way, searching for soundex codes will find similar-sounding
words.

Hm.  I'm not sure where the problem is.
