Multi field Lucene index

Hi,-

does it matter which field is added first into index when multi field
Lucene is used?

does that make difference at search time like if it matches first and
second field (which are fuzzy queries and AND-mandatory search term) and
ignore third and fourth mandatory (AND) fields (search terms)?

i saw this kinda behivor.

all the fields are TextField.

Best regards

Should not matter, AFAIK.

If your first MUST clause in a BooleanQuery fails to match for a
document, then there is no point for the engine to match further
clauses, right?

Of course if it were the case, but since the data is there for the third
and fourth, it should have brought the related data.

Best regards
