Hi,
I am trying to do something similar:-
Eg.
Input: (name:John AND name:Doe)
Output: ((firstName:John OR lastName:John) AND (firstName:John OR
lastName:John))
How can I extract the fields, change them and repackage the query?
Thanks,
Balaji

Having delved a bit more into the code it looks like every MultiTermQuery
descendant fails to implement the extractTerms method. This does make sense,
as it is not possible to list every term that satisfies a wildcard query.
I also notice that most Query classes including the MultiTermQuery's, hav
H. Assuming you called rewrite, I'm going to have to defer
that one, I'm not familiar enough with how range queries operate.
But what version of Lucene are you using?
Sorry I can't be more help

Thanks, that does seem good in theory. I can get the field from each of the
terms and add them to a Set to de-dupe.
However, in practice queries of the following nature seems to fail with an
UnsupportedOperationException:
field:a*
field:[a TO b]
Delving into the code a bit I see the following in
Did you look at Query.extractTerms? I think that'll work for you.
Note that the query must be rewritten, and that the set of terms will
have duplicate fields. i.e. if you search field1:Erick +field1:James
I expect you'll have two terms in the set that are on field1.

My code has been given a query string, which we parse into the Query object
and would like to get a list of fields from.
I'm assuming there exists a method to do so, as it seems like a useful
function. If not should I be parsing the string for fields myself.

Could you explain more about what you're trying to do? You're writing the
query
after all, so you probably already know what went into it.
Which shows that I don't understand what you want to do at all.
