Google Dorking

1. " "

A query with terms in quotes finds pages containing the exact quoted phrase. For example, “Larry Page“ finds pages containing the phrase "Larry Page” exactly.

2. OR |

OR for which you may also use | (vertical bar), applies to the search terms immediately adjacent to it. The first and second examples will find pages that include either "Tahiti" or "Hawaii" or both terms, but not pages that contain neither “Tahiti” nor “Hawaii”.

3. AND

Different from OR capital AND searches for pages using all words combined.

4. -

To find pages without a particular term, put a – sign operator in front of the word in the query.

The – sign indicates that you want to subtract or exclude pages that contain a specific term.

Do not put a space between the – and the word.

5. ( )

Allows grouping of operators and helps dictate order

Works with currencies, weights, temperatures, etc.
