I have MS Access database/table with attributes:

1. Word (text)
2. Lang (bool)
3. Translation (text)

It has 270,000 records.

* Database without any indexes and PKs is about 17MB (6MB compressed)
* Database *with* just indexes on Word and Lang is about 23MB (8MB 
compressed)
* Database *with* PK on Word and Lang is about 23MB (8MB compressed)
(I suppose that in this case indexes are made by default)

SQL response is dramatically slower without indexes.

I have to deploy this DB with the installation procedure, and I want to
save this 2MB ( 8MB - 6MB ).

The idea is to deploy the database without idexes and than make composite
PK (Word+Lang), or just indexes on Word and Lang at run-time, during
installation procedure.

The question is how to make (composite in this case) PKs or indexes
at run-time? I'm using ADO.
