Support for NumericRangeQuery in QueryParser

Hi,

I'm currently reading "Lucene in action (2nd edition)". At page 105 -
section 3.5.4, I'm reading the following paragraph:

---

QueryParser won’t create a NumericRangeQuery for you. This is because
Lucene currently doesn’t keep track of which of your fields were indexed
with NumericField, though it’s possible this limitation has been corrected
by the time you read this.

---

I'm using version 3.2 of Lucene and I'm not able to "queryparse" a
NumericRange syntax query. Can somebody tell me if this is already fixed in
Lucene? And most of all: in which version :-). I cannot find it using
Google :-( ...

Thanks!

Jochen

RE: Support for NumericRangeQuery in QueryParser [In reply to]

Hi Jochen,

the flexible query parser in contrib allows for numeric fields (you need to
configure it to "know" the types of fields, e.g. which fields are long
float,...). Alternatively use the code from my "Java Magazin" article a few
years ago and customize core's QueryParser by overriding the factory method
that creates range queries (I assume you are German and know this IT
magazine).

Hi Uwe,

Thanks for your answer. The alternative way was already familiar to me, but
thanks anyway ;-)!
I didn't know the "contrib" folder :-).

Thanks for your reply.

Kind regards,
Jochen

PS: I'm Belgian ;-) ...
