Glen Cathey says there are thousands of profiles which a standard LinkedIn search will not display.
The reason: they don't contain common keywords or they have skimpy, incomplete profiles.
1. You're looking for a software engineer with strong Java/J2EE experience.
You can search for “Java” but a lot of software engineers with Java experience do not mention “Java” in their profiles.
Proof: search J2EE -Java.
2. You’re looking for CPA’s. If you search CPA but not C.P.A you're going to miss a lot of people.
Proof: search "C.P.A." -CPA
You will also miss the people who list themselves as accountants but don't mention CPA or C.P.A Certified Public Accountant.
Proof: search Accountant -(CPA OR "C.P.A." OR "Certified Public Accountant").
Do you think an accountant at Deloitte, PwC, KPMG or Ernst & Young isn’t a CPA?
3. Search a current title of: (“software engineer” OR developer OR programmer).
Exclude the major technologies:
-(“java/j2ee” OR peoplesoft OR perl OR oracle OR SAP OR java OR j2EE OR .Net OR C# OR C++) in the keyword search field.
You will find software engineers at IBM, Accenture and Google who will not appear if you search the common keywords.
4. To find some people you have to limit your search to bland titles and likely companies.
