X-Ray searching is a term denoting a technique for searching LinkedIn (or other similar publicly available databases) via search engines such as Google or Bing.
The overwhelming majority of LinkedIn profiles are public, which leaves them open to being indexed by any search engine for finding using familiar Boolean search techniques.
Step 2: Build up your search string. The basic building blocks will be:
site:linkedin.com (inurl:pub | inurl:in) -intitle:directory -inurl:groups -recruiter
You then need to enter your keywords; in this example, let us try a very simple search for an iPhone developer with some kind of Agile experience.
site:linkedin.com (inurl:pub | inurl:in) -intitle:directory -inurl:groups -recruiter iphone (agile | tdd)
Next; location. A little different to a standard Boolean search, but only in ways which make it easier for us. Not too long ago, LinkedIn added the country code to the beginning of their URLs which makes for easier filtering; as a quick example;
site:uk.linkedin.com (inurl:pub | inurl:in) -intitle:directory -inurl:groups -recruiter iphone (agile | tdd) "London United Kingdom"
