If you set q.op=OR (and not as 'AND' you defined in your config), you will see the difference between your last two queries. The second last one will show 6 items and the last one still 5.
As is, with your custom config, booster query is added as one more clause in the search. q.op=ALL forces it to be a compulsory clause, rather than an optional (boosting one). FQ is always a forced compulsory clause. Maybe it accepts boosts, but all scores are ignored anyway (it is just 0 for fail and anything else for pass). Adding 'debug=all' into the query parameters (or defaults) would help you see that for yourself. But it does seem (in 7.2.1 I have here) that edismax seems to wrap both query parts in individual brackets. Maybe there was a bug that was fixed in eDismax only. No ideas there, except that most of the effort goes into eDismax these days rather than dismax. Regards, Alex P.s. My suggestion was actually to give the queries against STOCK examples. That would have made all these parameters explicit and more obvious. And perhaps would have allowed you to discover the minimum parameter set causing the issue without all those other qf and pf in the game.
