I agree that both of your examples are not good. And congratulation.to EN for deveoping a robust set of search options. My.problem is, How can can somebody who knows nothing about obscure search syntax do a.complex search. It has to be done so that somebody who is completely new to search can can easily compose a complex search without having to learn and memorize obscure arcane search syntax. It is hard to do, but with talent, time, perseverence, and the right supervision and testing, it can be done. But I do not think CorporatE EN is interested or willing.
And BTW, could we get spell check added to this message editor.
