On your Android phone or tablet, go to Advanced Search: google.com/advanced_search. Under “Find pages with,” choose the query field/s to: Include exact words or a list of words in your results. Remove words from your results.

First of all, even though the link is gone, you can still access this service by clicking on the gear in the upper right hand corner of Google next to "Sign in." Advanced search is on the drop down menu. So really the only change is two clicks instead of one.

On your computer, do a search on google.com. Below the search box, select the type of results: All, Images, Videos, or Books. At the bottom part of the search box, click Tools. Under Tools, click Advanced Search.

To deep search on Google: use quotes for exact phrases, use a minus sign to exclude words, type "site:" for specific websites, use tilde (~) for synonyms, and * for unknown words. "filetype:" finds specific file types. Use two periods (..) for numeric ranges.
