Web search overview
- Return up to 1000 results for a query
- Limits a search query to 10 words
- Indexes pages in HTML, PDF, DOC, PPT (any others?)
- Defaults to and
- + — must include (example: [michigan +ross])
- - — must not include (example: [michigan -ross])
- | — or (example: [michigan | ross])
- ~ — synonym (example: [~car], includes "car", "cars", "automobile", etc.)
- * — full word wildcard (example: [step * step]; finds documents with phrases such as "step by step", "step over step")
- site: — Restricts a search to a specific domain (or even a top-level domain). Example: "bba site:umich.edu". This means that "umich.edu" is where the documents are hosted and has "bba" in the content. It would not matter if the URL has "umich.edu" in the document URL — this looks for documents that are hosted at this particular site.
- intitle: — Restricts the search to Web page titles. Example: "intitle:tigers"; this looks for documents that have "tigers" in the document title.
- inurl: — Restricts the search to the Web page URL itself. Example: "Stanton MacDonald-Wright" inurl:library site:edu; this looks for documents that have the exact string "Stanton MacDonald-Wright" in the document and also has the word "library" in the URL and also is hosted at an educational institution (i.e., at an "edu" top-level domain, TLD).
- intext: — Returns pages if the query words are in the text of a Web page and not in the page's HTML. Only useful when searching for words that are HTML markup terms (e.g., body or html). Example: "intext:body"; this looks for documents that has the word "body" in the text of the document (and not in the title or in the HTML markup).
- link: — Returns a page if it links to the page you specify. This cannot be mixed with other special syntaxes or special searches. Example: ; explain.
- related: — In theory, this returns pages that are related (apparently, in some mysterious way) to the URL you specify. Example: related:http://www.amazon.com; this returns pages that are related to www.amazon.com. I defy you to define how Google has defined the term "related".
- info: — Returns the information Google has about a URL. It also sets up queries for "cache:", "related:", "link:", and "site:". Example: info:http://www.amazon.com; the best way to understand what this query does is to look at the Google page for this example.
Commands for Special Searching

- stocks: — To obtain financial/stock informaiton from a myriad of sources use this function. Example: stocks:c
- phonebook: — Used in two different ways..
