How can I improve my search?

Your first attempt at searching might not be successful. You may retrieve too few relevant records, or too many to be useful. The next few pages describe some tactics you can use to improve your search.

If you retrieve too few relevant records it could be that your search needs to be less restrictive.

If you retrieve too many records to be useful it is likely that your search has not been specific enough.

These are some ways of improving your search result. Experiment to see which works best for a particular search.
