Hi Ganesh,
I have already tried my own comparator, below is my code :
SortComparator comparator = new SortComparator() {
@Override
protected Comparable getComparable(String arg0) {
final String str = arg0;
Co
You need to write your own sort comparator
SortField(String field, SortComparatorSource comparator)

Subject: how to sort the result by ignoring case in lucene
Hi,
I have a query regarding the sorting techniques in the lucene i.e
if i apply the sort method to the search results, lucene is sorting the
results by, without ignoring case, so, how to apply the sort technique that
it should sort by ignoring case
i.e :
if the results value are : {ACB, abc, a
Hello all,
I am planning to use Filter for UserID and Date. I will not be able to cache
the Filter. I have to create this filter for every request. To my knowledge,
Filter will give faster results, only if it is cached.
Is it a good idea to use a filter or better to use query?

Ganesh

Hi Sergey,
quite a lot of numbers are possible for BigDecimal. Somehow the range
must be bounded.
Let's first draw the line where, for a given BigDecimal bd, the result

hi,
thanks for your suggestions.
actually, my original idea is that the same term may have different "weight"
in different doc.
of course the TF/IDF has already embedded some kind of term relavance to a
doc.
But I would like to explicitly set different "weight" to the same term in
diferent docs.
Thanks for the update, Mark. I guess that means I'll have to do the sorting
myself - that shouldn't be too hard, but the annoying part would just be
knowing where one result ends and the next begins since there's no guarantee
that they'll always be the same. Let me know if you find any information
Yeah, discussion came up on order and I believe we punted - its up to
you to track order and sort at the moment. I think that was to prevent
those that didnt need it from paying the sort cost, but I have to go
find that discussion again (maybe its in the issue?) I'll look at the
whole idea agai

This lives under contrib/queries, in both 2.3 and 2.4?

Hi Lin,
I guess you are looking at document boosting, if 'm right, you could
conditionally do this:
doc.setBoost(boostFactor);
where boostFactor is a float > 1.0 that boosts the doc with the boost
factor.
Also, you could also use
field.setBoost (boostValue) to boost a particular field in a documen
Thanks Ian

Hi
Lucene only indexes strings.
Hi
Lucene only indexes strings. The standard advice for numeric is to
pad to desired width with leading zeros, if likely to be used in range
searches. How varied are the numbers you're going to be working with?
I only work with stuff with 2 decimal places and tend to lose that.
e.g.
2.22 woul

Is there a way to change the value of stored fields that have not been
indexed without having to delete the document and re-index it. The fields I

You can do this. It's called adding a Payload. You can add payloads
during Analysis (Token.setPayload()) which means your code below will
need to be changed below such that you use the Field constructor that
takes in a TokenStream and wraps your input tokens. This TokenStream
will also n
No, they should not be compared. Scores are only relative to each
other for that given input query, despite what the queryNorm docs
say. The queryNorm was an attempt at doing it, but my understanding
of the research still indicates they are not comparable.
