Ignore Words

2003-01-21 Thread Heinz Bruhin

How can I show the words, which are ignored?

Example:
String searchString = "This is a Question"

The Ignored Words are: "is" and "a"

Lucene Turbine Service

2003-01-21 Thread Seth Weiner

Hi,

I'm fairly new to Lucene and am trying to create a 'simple' Turbine
webapp that will use Lucene for some indexing.  Has anyone written a
simple Turbine/Fulcrum Lucene service for searching and indexing
documents?

Thanks,
Seth Weiner

Yep. Look in Lucene Sandbox. Interesting you should ask, though,
because after about a year of using the LuceneSearchService, I've
recently refactored it out into a subsystem of its own...:-)

RE: Lucene Turbine Service

2003-01-21 Thread Seth Weiner

Thanks for the pointer!  Might I ask what the motivation for the
refactoring was?

On a separate note I just took a look at the service in the sandbox.  It
doesn't appear to support addition of documents to the index.  Shouldn't
be hard to add, just seems like a strange ommision.  Also, wouldn't it
be more efficient for the service to maintain a pool of IndexSearchers
rather than creating a new one for each search?  Or is there a problem
with holding one or more index searchers open on an index?  To
add/remove a document to the index, would all of the IndexSearchers need
to be closed, or is this safe to do?

The simple app I'm trying to write allows for the searching of an index
through a turbine webapp interface as well as the ability to upload a
document through the webapp to be added to the index.  If the document
exists in the index it's deleted and then the new version is added.  If
anyone's already done this feel free to share;)  And while you're in a
charitable mood, my next step is to take the Lucene service and make it
an XMLRPC webservice.  Thoughts and suggestions on that idea are greatly
appreciated.

Thanks,
Seth

Re: how to join 2 queries togther

2003-01-21 Thread Charles

Hi everyone,

First of all I'd like to thank you guys for developing a great search engine
framework. I've tested it out and it works flawlessly (and really fast too).

Right now I plan to create a more advance search capability. I understand
how to construct the Query object using the QueryParser, but I would like to
know how I can add in different types of queries (like range, terms,
boolean) all into one. I'm not sure if I can do this with the QueryParser
and am looking for information on how to manually construct a Query object
so i can combine all these requirements.

Here's what I want to do: I would like to have the user select values from a
combo box (e.g. Price range, Area, Country, Number of rooms, land area, is
Freehold or Leasehold etc). From what I gather this involves several type of
queries including RangeQuery (for the price range), a TermQuery,
BooleanQuery etc. So the question is how do i combine all these types of
queries into one so I can obtain a single Hits result that matches all these
requirements?

Any advice or urls is very much appreciated.
Charles

Range queries

2003-01-21 Thread Tatu Saloranta

My apologies if this is a FAQ (which is possible as I am new to Lucene, 
however, I tried checking the web page for the answer).

I read through the "Query syntax" web page first, and then checked the 
matching query classes. It seems like query syntax page is missing some 
details; the one I was wondering about was the range query. Since query 
parser seems to construct these queries, I guess they have been implemented, 
even though syntax page didn't explain them. Is that correct?

Looking at QueryParser, it seems that inclusive range query uses [ and ], and 
exclusive query { and }? Is this right? And does it expect exactly two 
arguments?
Also, am I right in assuming that range uses lexiographic ordering, so that it
basically includes all possible words (terms) between specified terms (which 
will work ok with numbers/dates as long as they have been padded with zeroes 
or such)?

Another question I have is regarding wildcard search. Page mentions that there 
is a restriction that search term can not start with a wild card (as that 
would render index useless I guess... would need to full scan?). However, it 
doesn't mention if multiple wildcards are allowed? All the example cases just 
have single wild card?

Sorry for the newbie questions,

-+ Tatu +-

ps. Thanks for the developers for the neat indexing engine. I am currently 
evaluating it for use in a large-scale enterprise content management system.

Re: how to join 2 queries togther

2003-01-21 Thread Otis Gospodnetic

It should all be pretty clear from the API javadocs.  Take a look at
BooleanQuery, which is that single query that you can add other
queries.
Good luck.
