The problem with results is that Lucene collects not all, but only N top results (N is set by you). And this is a good idea, since it reduces time for search process heavily, yielding only results you may be interested. Though you can set N to some very big number, make one search for each term in query and then combine results, I actually do not recommend doing this.

On the other hand, You can combine your terms before searching, not after. I'm not familiar with zig-zag join, but most probably you'll have to create new syntax for query and force QueryParser use your ZigZagQuery (or whatever you call it). For examples of implementation see Query subclasses source code.
