That version doesn't work as expected for queries where all the terms are required, it parses them in a way so that every term needs to be in every field.
I'm not sure whether we are thinking alike here. Judging from the code in 1.4.2, I expect the query "X AND Y" to be evaluated as:
(field1:X AND field1:Y) OR (field2:X AND field2:Y) OR ... (fieldn:X AND fieldn:Y)
Is my interpretation of the code correct? If so, then I agree that this is somewhat counter-intuitive. When I enter this query, I would except it to be evaluated as:
(field1:X OR field2:X OR ... fieldn:X) AND (field1:Y OR field2:Y OR ... fieldn:Y)
In other words: both terms have to appear in at least one field of the document and this does not necessarily have to be the same field. This way it doesn't matter whether the indexer uses one field or several fields to index his contents. Would your change result into this behaviour?
