Hello,

I'm using htdig-3.2.0b1 on a Debian GNU/Linux SMP workstation.

search_algorithm directive is :
   search_algorithm: exact:1 endings:0.1 prefix:0.1

A search request using the word "matsu*" returns the following header:

--- cut here ---
Search results for '(matsu* or matsuda or matsuda or matsuda or
matsuda or matsuda or matsuda or matsudas or matsue or matsue or
matsugaoka or matsugaoka or matsugaokacho or matsugaokacho or matsui
or matsui or matsui or matsui or matsui or matsui or matsui)'
--- cut here ---

I have 6 occurences of the word matsuda in the header.

If I use the word request "matsuu*" i have the following header :

--- cut here ---
Search results for '(matsuu* or matsuura or matsuura or matsuura or
matsuura or matsuura or matsuura or matsuura or matsuura or matsuura
or matsuura or matsuura or matsuura or matsuura or matsuura or
matsuura or matsuura or matsuura or matsuura or matsuura or matsuura)'
--- cut here ---

Fortunately the directive max_prefix_matches is 20, if not I would have
a lot of "matsuura" occurence...

The seach results is good. Only the headers are strange.

Could somebody explain this behavior ?

Thanks.
