I think the nominal minimum word length is 4 so 'fiat' will not be indexed.
This can be modified however.

Jamie,
I think your approach of a cross-reference table is a good start. This is
similar to creating a stemming index. Perhaps you might like to look into,
for example, some perl Modules for stemming (like Linga::Stem) to further
reduce your data space.
Perhaps since there may be a large
If you only interested in getting the overall sum from the child tables you
could try the following:
1)
Change your child create statements to:
CREATE TABLE child1
(
auto_nr int(11) unsigned zerofill NOT NULL,
link int(11) unsigned ,
value int(11),
PRIMARY KEY auto_nr(auto_nr),
KEY
I presuming you are expecting more results from the first select statement,
hence the reason and indicating this in the second, should then your first
statement be:
select edate from traffic where year(edate)='2001' group by
edate;
