To make your search more effective start with shorter keywords or sku's first. The more complex the query, the less effective the search will be or use quotes to separate terms.
If a wild card (*) is used, oc*, will return any word starting with "oc" such as "occupational".
The search function uses inflectional matching. If you search for "teach" other forms of the word like "teaching" will appear. You can exclude by using "not" between search terms: Example: teaching not college
