Hy,
i use Lucene to index a SQL-Table which contains three fields: a index-field,
the text to search in and another field. When adding a lucene document I let
Lucene index the search-field and also save the id along with it in the
lucene index.
Uppon searching I collect all ids and add them to
Maybe this:
SpanNotQuery(interested, SpanNearQuery(not,interested))
with a SpanTermQuery for each term?
Thanks, Paul. This is working well for me and I can happily use multiple
SpanTermQueries embedded in a SpanOrQuery in place of each of the single
words in your example.

Hi Erick,
The fields that are missing are sort of primary keys and they exist in
all the documents (including those that were returned in my search
results) when I browsed through the index using Luke. And the field
names are exactly the same all in the same case. I never get the three
field value
There is no requirement that every document contain values for every field.
Doc A could have fields z, y, x, and Doc B could have fields x, w, v. So,
when you say "some of the values are being returned as null", do you mean
that you *never* get any values for some field or you get values for a fie
Hi,
I indexed some XML files using Lucene. When I open up the index using
Luke, I can see that all the fields are stored correctly in the index.
But, when I try to grab the fields from the hits, after searching, some
of the values are being returned as null. Any suggestions about what
might be
Thanks Otis.
When two segments are merged into one, are they merged contiguously,
so that the individual .del files for the individual segments will no
longer be needed? Or are the .del files merged into a single larger
.del file for the new segment?

Hi Monsur,
You don't need to reindex everything after changing merge factor. As for
growing the .del file, I believe the .del file simply keeps track of documents
that have been deleted (and should thus not show up in search results). Thus,
I think you can let the file grow, although at some

I have a system of 2 servers, one to index and one to search. The
index server updates the Lucene index and then copies the 200 meg
index over to the search server. Originally, the index server would
optimize the index before copying. To improve performance, I stopped
optimizing, dropped the me

Hi,
since I use many wildcards, I get the exception, that the number of boolean
queries exceeds the default value (1024).
I could simply increase the value to like 10,000 or something
What would be the trade-off of using a high max value?
Thanks!

Correct, because it's final you cannot change it directly.

Maybe you didn't close / open your writer/reader and that you where
searching with a snapshot of the old index. And that after you had closed
the writer and opened a new reader you got the correct result..?
