# Data Mining on the Internet with Google

Expand your power of Google.

Google (and many other search engines) has the ability not only to search on keywords, but also using a more “database-ish” query language to really narrow down your search results. The following is a summary of a few of the most useful lesser known features.

Helpful tips include:

- To include phrases quote the words together (straight quotes). For instance, “Bill Clinton” returns results as most expect whereas a search for Bill Clinton will return pages with the two words anywhere in the resultant page.
- To exclude words in a search, prefix the word or phrase with a minus sign (-).
- To restrict a search to a specific domain such as <span class="caps">UCLA</span>, use the modifier inurl: (thus, for <span class="caps">UCLA</span> append inurl:ucla.edu to the search).
- If you prefer a form interface for advanced queries, click on "Settings" &gt; "Advanced search" or go directly to [https://www.google.com/advanced\_search.](https://www.google.com/advanced_search)
- Go in to "Settings" &gt; "Search settings" to display more than ten results per page.

Here are some pages for crafting better searches.
