Hi Doug,
Thank you for the details, it helps me lot!
There are no reserved keywords whatsoever, the issue is something else. I have noticed, that you have keyword exceptions set as following:
[code]for, in, on, ‘s[/code]
The problem is, that the for, in and on keywords will be replaced anywhere within the search phrase, meaning that entering Spring will actually search Sprg.
Instead, I believe you meant to place these keywords into the other configuration box, so that for, in and on are replaced only as whole words. Changing the configuration as following, will do the trick and resolve the problem.
