Revising and refining your search (too many results).
Answer
You will find that nearly all databases give you various filters to help narrow down your search results. These usually include filters for date, language or material type.
It can also be useful to try searching for your keywords in specific fields (e.g. the title or abstract fields.) This will again help to limit the number of results and make your search more focussed. You can combine searching in specific fields with using filters.
In some databases such as LibrarySearch you will need to go to the advanced search option to access the full range of filters and search options.
