I have changed the search system slightly to (hopefully) give better results. Previously you could use wildcards e.g. Car* would give Carlisle and Cardiff. This was hardly ever used and the search tended to give very long lists of unhelpful results.
You now can't use wildcards but the results should be better. For more general QOF queries over many web sites the Google search is still there. It searches on selected QOF related sites without all of the stuff about GnuCash and Hebrew characters you tend to get on a full Google search.
