As you may already aware, indexing will improve the performance when used properly and not possible to explain everything here.

If you feel, your query is slow (taking more time to give the result) then you may have to look at the executioin plan which will give you and indication where the bottle neck is. The execution plan can be enabled by pressing "CTRL +M" prior to the query execution and once the query is executeted you will see an another tab on the result pannel ( there will be three pannels namly results,message,execution plan) and at times the execution plan will suggest an SQL INDEXING script for fine tuning the query - please do this on a test dataase

I would recommand you to do some googling on this and read some tutorials / ariticles on this to understanding the indexing and the best way forward
