List other restrictions you can put on search results.
Search Result Restrictions
The techniques described in the previous lessons have all involved ways to limit a search through the search query.
Many directories and search engines also offer selection options (usually on the Advanced or Power search page) that limit the parts of their database that will be searched for matches. Combining any of these options with search query terms that also limit the search is a powerful method of focusing a search that is looking for information that is restricted by its nature to a certain portion of the Web or the Internet
(.edu or .mil Web sites, for example, or a specific country).
The following SlideShow illustrates some other ways that search engines let you limit your searches:
Other options to limit a search
Filter your search results
Do a search on Google.
Choose the type of result you want to see, like Images or News, by selecting a type under the search box. Click More to see extra choices.
Below the search box, click Search tools to see more filters you can apply to your search. The Search tools you see will be different based on your search and the filters you've already used, so you won't see all the options every time.
To remove any filters you've added through Search tools, click Clear.
How to Limit Your Search
For all or some of the search types in this collection, you may be able to enter criteria to limit your search.
For example, you may want to search for documents with a specific publication date, only for documents with images, or just video.
If available for a given search type, the search limiters are generally displayed below the search term input box.
If the search limiters are not currently displayed, click the More search options link found on the search page.
Click the Hide search options link if you no longer wish to see these options.
The ability to specify search limits or remove them may also be available from the results list, depending on the type of search performed.
