Is it ok to apply indexes on all the columns involved in the WHERE clause of queries? Our database is a read-only VLDB database.

Other than the space needed by these indexes, I'm not assuming there will be any bad repercussions by adding them because there are no updates/deletes/inserts into this database.
I'd really appreciate all the experts' advices.

If you mean putting single column indexes on every column, probably not.

If your table is truly static and you have the space then add as many indexes as you need to cover the queries being issued. Go ahead and use a FILL_FACTOR of 100 (or 0) too. Another thing you can do to help performance is to move the table and its indexes to a new FILEGROUP and then mark the FILEGROUP as read-only.
