Hi,
We are having an issue while indexing Chinese Documents in Lucene.
Some background first:
Since CJK languages doesn't have space between words, we first have to
determine the words from sentences. e.g.
a sentence containing characters ABC, it may be segmented into AB, C or A, BC.
the proble
Very interesting the link you suggest me Mr Grant Ingersoll.
Let see if I understand how the ranking issue in lucene could be implemented:
1. First I must create my own query class extending the abstract Query
class. The only method I must implement from this class is toString.
Is right this ?
Hi Tobias,
I had the similar problem with lucene custom sorting about two years ago.
Please take a look at these two email threads:
http://www.gossamer-threads.com/lists/lucene/java-dev/39100
http://www.gossamer-threads.com/lists/lucene/java-user/38016
It seems like they did not make any patch f
Hi,
We have implemented a custom sort following the pattern in Lucene in Action.
Unfortunately this has led to quite serious memory problems. When analyzing
those (with a profiler) it seems that there are as many remaining instances of
our SortComparatorSource as there have been queries against th
What about http://www.openxml4j.org/? Any experience there?

You might also consider asking on the Tika (a Lucene subproject
currently in Incubation) and Aperture project sites (http://aperture.sourceforge.net
). Not sure if you will have any luck, but they are also focused on
the extraction problem and may have thought more about it.

Hello,
I know this has gone around a bit but anyone had any success with
pulling text from Office 2007 files? Any recommendations?
Thanks,

Any other info or code snippets? I sort on multisearchers all the time
and have never seen that behavior.

Hi,
I have few Indexes with the same structure.
I'm using MultiSearcher to search into those indexes and when I try to
sort the result by field the result is sort by field and by index (we
have all results from index1 and then index2,...) but I would like to
have the result sorted on the all result
OK, I've opened https://issues.apache.org/jira/browse/LUCENE-1048 to this issue.
Thanks Nikolay!

The FieldCache already stores only one string per term,
I suppose you have for about 5 minutes to display a single search ? :-)
Perhaps before pointing out your possible solutions, you might better
start describing your functional requirements, because your suggested
solution is headed for problems. So you need custom ordering, check out
