How to remove the possibility to search the parts of a compound word with hyphen

Hi all:

I have been searching the mailing lists about hyphens but I coudn't find
the answer to this question:

Is it possible to remove the possibility of searching the parts of a
word which include a hyphen? I know that the default parser identifies
all possibilities (the compound word and the individual part ones), but
I would like to make possible to search only for the compound word, but
not for the parts.

Using one example of the parsers section in documentation, i would like
to make possible to search lógico-matemática but not lógico or
matemática individually.

Would have I to write a new parser or are there any configuration issues
to do this?

Thanks,
