I found Michael interface's text representation / query preview really neat. Another useful preview would be the amount of results the query will get (or even better, also the first few results). Previewing the outcome of the query allows the user to work on the expression only as necessary, and avoids getting no results after building a complex query.
Alas, I am not thrilled by the use of "AND" and "OR" operators in the GUI, as it can lead to confusion when having more than two conditions or nested logic. Using "all/any of the folowing conditions" benefits from a grammar that, by definition, avoids those problems. -- Santiago Bustelo // icograma Buenos Aires, Argentina . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
