How to improve the performance of a query?

I have a table called DMPD_Product_Lookup_Dom. It is a lookup table which contains values for certain fields of other tables in the database.
This takes long time to run.
Is there any way to improve performance of this query ??

DOM1.Value_Description AS 'AdminCategoryDesc',
BNAD.Benefit_Component_Name_CD AS 'BenefitAdmin',

Yes, the tables mentioned have indexes. But i want to know is there any other way to improve the performance of this query.|||Unfortunately you didn't provide specific answer.
To help you I need to see all index compositions.
Some people think they have indexes but it could be that they are not the once that such query will use.

To view if your query uses indexes in SQL Query Analyzer go to Query Show Execution Plan.
Execute your query and point to each item and see if your indexes are actually used.|||well the performance can be boosted using the appropriate filters in the FROM clause itself. Try to use INNER and the other different appropriate joins in the clause.The default join is the CROSS join which is the worst join. So try to filter out the results as much as possible in the FROM clause. Definitely the performance will be boosted up to some instant.|||
