Using Search Operators

        
    The webpages maintained by the Google Help Center have text describing more than 15 various search options.The Google operators:
       
    1 OR – Search for either one, such as "price high OR low" searches for "price" with "high" or "low".
    2 "-" – Search while excluding a word, such as "apple -tree" searches where word "tree" is not used.
    3 "+" – (Removed on 10/19/11) Force inclusion of a word, such as "Name +of +the Game" to require the words "of" & "the" to appear on a matching page.
    4 "*" – Wildcard operator to match any words between other specific words.
    5 "~" – Search using similar terms, for example "speaker ~cable" will also return search results for "speaker wire".
    6 ".." – Search for numbers within range, for example "war 1920..1940" and "5.. kg trout".
       
    Some of the query options are as follows:
       
    1 define: - The query prefix "define:" will provide a definition of the words listed after it.
    2 stocks: - After "stocks:" the query terms are treated as stock ticker symbols for lookup.
    3 site: - Restrict the results to those websites in the given domain, such as, site:www.acmeacme.com. The option "site:com" will search all domain URLs named with ".com" (no space after "site:").
    4 allintitle: - Only the page titles are searched (not the remaining text on each webpage).
    5 intitle: - Prefix to search in a webpage title, such as "intitle:google search" will list pages with word "google" in title, and word "search" anywhere (no space after "intitle:").
    6 allinurl: - Only the page URL address lines are searched (not the text inside each webpage).
    7 inurl: - Prefix for each word to be found in the URL; others words are matched anywhere, such as "inurl:acme search" matches "acme" in a URL, but matches "search" anywhere (no space after "inurl:").
       
    The page-display options (or query types) are:
       
    1 cache: - Highlights the search-words within the cached document, such as "cache:www.google.com abc" shows cached content with word "abc" highlighted.
    2 link: - The prefix "link:" will list webpages that have links to the specified webpage, such as "link:www.google.com" lists webpages linking to the Google homepage.
    3 related: - The prefix "related:" will list webpages that are "similar" to a specified web page.
    4 info: - The prefix "info:" will display some background information about one specified webpage, such as, info:www.google.com. Typically, the info is the first text (160 bytes, about 23 words) contained in the page, displayed in the style of a results entry (for just the 1 page as matching the search).

These are some google search syntax by which we can search better.
