We solved it here,
There was a problem in the query, we removed the t1 at the 'group by'
section. The problem was really a sintax error in the code not in the
server.

You're misunderstanding something. When you create an index, all the
rows in the table are

For anyone who is interested the thing that worked and brought the query
down from 8 minutes to 5 seconds was separating out the JOIN to remove the
OR. I made it into two queries and UNIONed them together and it all works
beautifully now.
Thanks.

Do you have separate indexes on:
Table1.ID
Table2.ID
Table1.Field1
Table2.Field1
Table1.Field1
Table1.Field2
Select*
FROM Table1 as a
INNER JOIN Table2 as b ON (a.ID = b.ID or (a.Field1 = b.Field1 and
a.Field2 = b.Field2))
WHERE bla bla bla

No, we tried individual indexes and then one big grouped index but not
individual indexes on each of the fields. Adding the index actually added a
few seconds to the query so we weren't sure if that was the way to go.
I'll try this, though.

Tried to make the indexes separate and did an EXPLAIN and no performance
increase and this is what the explain says:
id select_type table typepossible_keys

Hmm, that is weird. Actually, I had the same issue (sort of). I was grabbing
some data from a MySQL instance on an OS X workstation. I had shared the
tables in Access via ODBC. I'd start to update the MySQL DB and get an ODBC
error. Usually I'd get about 93 rows done (out of 1000 or so).

Create a merge table of the year 2000 and year 2001 tables as follows.
Then run your select on the merged table.
You can then drop the merge table if you don't need it anymore.
