lucene.net version query
Hi,
What is the difference in the v1.9.1.3 dll and v2.1.0.2?
We were initially using v2.1.0.2 dll but we need various other Analyzers
liked German etc, which is present in v v1.9.1.3 dll.
Is there any drawback in using v1.9.1.3 other than v2.1.0.2?
Thanks,
Sudhanya

* Since Lucene.Net is supposed to be compatible with its Java version, it is
better to keep the track of API changes and new features between 1.9 and
2.1 in Lucene.Java lists
* As far as I can remember, Lucene.Net 1.9 contains only German and Russian
Analyzers. Since they are in the contrib section of Lucene.java, they must
have been removed from the Lucene.Net core(without moving to contrib of
Lucene.Net :-( ).
* After the release of 2.1.0.2, a lot of bug fixes have been made. So if you
don't intend to use v1.9.1.3, I strongly advice to upgrade to v2.1.0.3.

Re: Where is the 2.1 dll for Lucene.Net?
Posted by Foo JH <jh...@extracktor.com>.
Hello David,
Yah, I'm looking for the source but this link (source release) doesn't load:
https://svn.apache.org/repos/asf/incubator/lucene.net/
And this link (stable zip'ed release) doesn't list either:
http://incubator.apache.org/lucene.net/download/
Any help is appreciated.

RE: How to perform search within Search Results recursively
Posted by Michael Siu <mi...@hotmail.com>.
Thanks for the reply.
On the other hand, how to do a query for the following situation:
- One index has the content index for a list of documents and a key to the
document. That means the Lucene document of this index contains 2 fields:
the 'content' and the 'key'.
- another index has the some data indexed associated with the 'key' in the
previous index. The Lucene document of this index contains several fields:
the 'who' that contains some data and the 'key' that _points_ to the
document in the first index.
Sample data:
Index_1: [key] [content]
Abc "blah blah 123 ..."
Xyz "123 321 a nice day ..."
Index_2: [who] [accessed] [key]
David 1/1/2007 Abc
Someone 1/2/2005 Abc
Guess 12/1/2000 Xyz
Harry 1/1/2008 Abc
Sandra 1/1/2003 Xyz
As shown, the [key] field in Index_2 has repeated value that _points_ to the
[key] values in Index_1. How do I make a query for the following:
Find out all documents in Index_2:
- [who] is in range of 'David' to 'Guess' and
- [accessed] in range '1/1/1900' to '1/1/2010' and
- [key] associated [content] in Index_1 that contains the term 'blah'
I know this is more SQL like query. Is Lucene capable of doing this type of
query that needs associations among index files?
Thanks in advance.

Hi,
I am a newbie to Lucene and Lucene.net. I am wondering if it is possible to
perform search within search results recursively. That means if I initially
perform a search on all fields in a query string. Then I want to perform
another query string on the search results from the previous search and so

to perform search like this with Lucene or Lucene.net?

RE: How to perform search within Search Results recursively
Posted by Digy <di...@gmail.com>.
I don't think that there are good-and-simple solutions for these kind of problems
[first make a search on indexA, then using the results, make a second search on indexB].
1- If the first search returns more than "max-term" results, then second search will throw an exception.
2- To avoid the exception, setting max-term ,for ex, to MaxInt would mean storing all results(not only top n results) of the first search(which can be very huge) in memory, and also degrading the performance of the second search.(using "Hits" object can also be a nightmare in this situation. See http://wiki.apache.org/lucene-java/ImproveSearchingSpeed )
3- Depending on the nature of the data, choosing the right index to perform the first search can be very tricky, and starting the search with the wrong index can VERY-badly effect the overall search performance.

Michael,
This sort of association between to indexes can be done, but is not natively supported in Lucene. One solution that comes to mind would be to only have one index, adding the [content] field to Index_2 and omitting the [key] field all together. This would result in duplication of indexed data, but I don't think of an index as being normalized like a database.
If you wanted to stay with the 2 index format, you would need to run two separate queries:
1) find [key] associated with [content] in Index_1 that contains the term 'blah'
2) query Index_2 with the following boolean clauses:
+[who] is in range of 'David' to 'Guess'
+[accessed] in range '1/1/1900' to '1/1/2010'
+[key] found in querying Index_1

Michael,
Thank you for the hint. I need to stick with the 2 index way to avoid duplicates in [content] for the same data (the content can be big).
One problem with your solution: what if the query of 1) returns more than 1 key? How do I include the list of all the 'keys' in the second query?
Thanks again.

Michael -
You can create a BooleanQuery with all of the keys in clauses with BooleanClause.Occur.Should to create a "key1 OR key2 OR..." query, then add that query as a clause with BooleanClause.Occur.Must to ensure that the documents match at least one of the keys.

Subject: How to perform search within Search Results recursively
Hi,
I am a newbie to Lucene and Lucene.net. I am wondering if it is possible to
perform search within search results recursively. That means if I initially
perform a search on all fields in a query string. Then I want to perform
another query string on the search results from the previous search and so
on. This is similar to search within results in Google. How is it possible
to perform search like this with Lucene or Lucene.net?
Thanks in advance.

It can be done with "ANDing the new query with the previous one" (like
google does).

LINQ to Lucene
Posted by Vijay Santhanam <vi...@spectrumwired.com>.
Hi All,
There's a myriad of interesting linq provider projects coming out and
there's one in particular I hope you find interesting, linq to lucene.
http://www.codeplex.com/linqtolucene
It's nowhere near completion, but the main developer has integrated plenty
of nifty query and index features.
If anyone in this list uses C# 3.0 and framework 3.5, please check out
linq-to-lucene and provide feedback.
The core LINQ provider has been implemented, and I think the rest of the
work involves filling out and cleaning up the API.

RE: Strange unsearchable "releas"
Posted by Digy <di...@gmail.com>.
I tried it with the following code and also within the luke. Everything
works fine.
DIGY
Lucene.Net.Analysis.Snowball.SnowballAnalyzer sbAnalyzer = new
Lucene.Net.Analysis.Snowball.SnowballAnalyzer("English");
IndexWriter wr = new IndexWriter("TempIndex", sbAnalyzer,true);
Document doc = new Document();
doc.Add(new Field("searchText", "release", Field.Store.YES,
Field.Index.TOKENIZED));
wr.AddDocument(doc);
doc = new Document();
doc.Add(new Field("searchText", "create", Field.Store.YES,
Field.Index.TOKENIZED));
wr.AddDocument(doc);
wr.Close();
IndexSearcher searcher = new IndexSearcher("TempIndex");
QueryParser qp = new QueryParser("searchText", sbAnalyzer);
Query q1 = qp.Parse("release");
Query q2 = qp.Parse("create");
Hits hits1 = searcher.Search(q1);
Hits hits2 = searcher.Search(q2);
MessageBox.Show(hits1.Length().ToString() + " " +
hits2.Length().ToString());
àoutput: 1 1

I tried both KeywordAnalyzer and Simpleanalyzer, same result, I clicked
on the "Explain structure" button and got something like:
-BooleanQuery: boost=1.0000
clauses=1, maxClauses=1024, scorer14=false
-Clause 0: +
TermQuery: boost=1.0000
Term: field='searchText' text='releas'
Is that what you like to see?

Re: Strange unsearchable "releas"

seems an estrange behavior, ¿What happen if you query the index with
your application and lucene.net?
However, you can debug the lucene code and watch what happens inside
lucene, and what are the diferences between the 2 searchs.

have you watched what is the analyzer that is luke using?
if you provide the explained query in luke we can help a bit more.

Strange unsearchable "releas"
Posted by Min Yin <yi...@AI.SRI.COM>.
Hello there!
We are using Snowball so in our lucene database index there is this
entry of "releas" (which is the snowball processed "release") under
field searchText, I can see that with Luke, but if I do a
"+searchText:releas" search within Luke, nothing is returned. Other word
like "creat" (which is the snowball processed "create") works great.
"releas" seems to be the only "specify" word I found so far.
Any idea? Thanks in advance.

Re: Where is the 2.1 dll for Lucene.Net?
Posted by Foo JH <jh...@extracktor.com>.
Can I safely assume that any compilation of the api will generally work
across the board? Can any kind soul contribute to the binary?
I'd only need one for the x86 platform.

I also was about to advise to build it from source after extracting source
using TortoiseSVN ; but you are right link
https://svn.apache.org/repos/asf/incubator/lucene.net/
is broken

Hi there,
I see people referring to 2.1 of Lucene.Net. I also see the NDocs for
2.1 But I don't see SVN or binaries for this API. Where can it be found?
Thanks.
