I had an email relating to the phrase searching, it highlighted that a search for “e-learning” was generating huge amounts of irrelevant results. It appears that the hyphen, within the phrase searching, causes confusion!
After a bit of trial an error the appropriate way appears to ditch the hyphen and simply search for “e learning”. The result:
I expect most will agree this is a better, more manageable, result!
Thanks Feargus for highlighting the issue!
