Up until recently, search results in LinkedIn Recruiter (LIR) and in (any) personal account were the same. LIR provides more results available for viewing for a given search and better results visibility (and also some facets that are not available in a personal search).
This has changed dramatically.
If you have a LinkedIn Recruiter account, you must read on.
Here are three examples of searches, compared side-by-side for a personal vs a LIR account. (Guess, which account provides more results?)
Personal account: 150 results.
Click on "View Results in Recruiter" ...
... the same search shows 43 results:
So: in the EXAMPLE #1 the numbers are:
In the above examples, LinkedIn Recruiter provided way fewer results than a personal account. It shows anywhere from about 50% to 20% (!) of the numbers of search results that a member would get with any personal account - including the Basic.
I do have some guesses for the reasons of the discrepancies, but I can't be sure. There's no official documentation or information in blogs about this, as far as I can tell. I don't think the discrepancies are caused by software bugs. My best guess is that these are "side effects" of developing Galene and the Economic Graph. I have seen some cases where the discrepancies are the other way around: LIR shows more results than personal, for no apparent reason.
Take a note of it. Don't lose matching results. I'd recommend to search from both personal and from LIR and, perhaps, X-ray as well.
