If you want to create complex indexes, you need to inherit _auto_init method of the model and execute a CREATE INDEX (using cr.execute) statement after you call the super.

If you just want to create per column index - PostgreSQL is capable to combine index, just add select=1 in the column definition, like so:

'name' ; fields.char('Name', size=64, select=1)

If you are interested on how a table and it's related objects, read the _auto_init method of BaseModel.

Thanks Ivan , Yes I too found the same by referring "account_move_line" object... However I came over across 2 kinds of select parameters, i.e "select=1" means Basic Search, "select="2" means Advance Search... Any idea what exactly is the difference... In database level I see no difference between these two indexes..

I think that has something to do with whether the field will be displayed as search criteria by default in a search view. If select=1, a default search view will have the field added. At least that is what I've experienced with v6. I'm not sure whether it is still valid for v7 and v8.
