Apparently I'm not the only one confused by the search results. I expect this will be reported
repeatedly by people who think the search function is broken when they get results like you did.
I reported it, but the issue was closed as invalid:

letters between.
This only happens with the OB System Browser. Go to system>settings>code browsing>default browser and change it from 'OBSystemBrowserAdaptor' to 'Browser'. That one only finds proper substrings.
