I find this helpful when I can not use the search function on the boards.
site: If you include [site:] in your query, Google will restrict the results to those websites in the given domain. For instance, [help site:
www.google.com] will find pages about help within
www.google.com. [help site:com] will find pages about help within .com urls. Note there can be no space between the "site:" and the domain.
This functionality is also available through Advanced Search page, under Advanced Web Search > Domains.
allintitle: If you start a query with [allintitle:], Google will restrict the results to those with all of the query words in the title. For instance, [allintitle: google search] will return only documents that have both "google" and "search" in the title.
This functionality is also available through Advanced Search page, under Advanced Web Search > Occurrences. v
intitle: If you include [intitle:] in your query, Google will restrict the results to documents containing that word in the title. For instance, [intitle:google search] will return documents that mention the word "google" in their title, and mention the word "search" anywhere in the document (title or no). Note there can be no space between the "intitle:" and the following word.
Putting [intitle:] in front of every word in your query is equivalent to putting [allintitle:] at the front of your query: [intitle:google intitle:search] is the same as [allintitle: google search].
