RE: Boolean AND query
Hi, To achieve what you want, you need to use the required operand (+) --Daniel -Original Message- From: Aruna Raghavan [mailto:[EMAIL PROTECTED]] Sent: quinta-feira, 21 de fevereiro de 2002 13:44 To: 'Lucene Users List' Subject: Boolean AND query Hello, Has anyone run into problems with boolean AND query? Basically, I am using the following code to do the query to look for 10060 AND 10040 BooleanQuery bq = new BooleanQuery(); Analyzer analyzer = new StandardAnalyzer(); Query query = QueryParser.parse(m_strKeyword, pageText, analyzer); bq.add(query, true, false); In this case, I am just using one query to add to bq but there can be more. I am getting correct results when 10060 AND 10040 exists in the document. But when one of them does not exist, I am still getting the same results. In other words, AND seems to be acting like an OR. I noticed this in the latest RC4 as well as an older lucene build from before lucene joined jakarta.

RE: Lucene Build Instructions
I agree. I think this should be fixed before the official release (I've had trouble building Lucene and I've seen messages from other users with the same problem). Can you make the changes and submit the patches?

The best option would be having all properties defined in build.xml and eliminate build.properties. Each user would be responsible for the local configuration in a build.properties file (javacc.home would be defined there) and a sample build.properties would be provided to help this process. --Daniel $ pwd /work/lucene-1.2-rc3-src $ cat .ant.properties javacc.home=/work/javacc2.1/bin/lib $ ls /work/javacc2.1/bin/lib/JavaCC.zip /work/javacc2.1/bin/lib/JavaCC.zip $ ant Buildfile: build.xml init: javacc_check: [echo] ## JavaCC not found.

For example, if you installed JavaCC in /usr/local/java/javacc2.0, then set the javacc.home property to: javacc.home=/usr/local/java/javacc2.0/bin/lib If you get an error like the one below, then you have not installed things correctly.

RE: [PATCH] Re: Lucene Build Instructions
From: Erik Hatcher [mailto:[EMAIL PROTECTED]] Ok, here's the patch. It includes my earlier patch with the docweb additions (see my previous patch for the related code). All I really did was paste in build.properties. Yep, that's what I was expecting to see but since you know Ant a lot better than me I thought that maybe you'd come with something different ;-) Don't know about the others by I vote for incorporating these changes on the next release.

RE: Lucene beginner
Hi Saima, To run the demo, you have to have lucene-demos-1.2-rc3.jar and lucene-1.2-rc3.jar in your context classpath. If you're using Tomcat, you can either have a directory under your application WEB-INF named lib with the jars or put them under Tomcat's common/lib (the former option is prefered, since probably other applications don't need access to these jars). Don't forget to configure the demo file configuration.jsp, so that indexLocation points to the place you've created your index. --Daniel -Original Message- From: Saima Shaikh [mailto:[EMAIL PROTECTED]] Sent: terça-feira, 12 de fevereiro de 2002 07:40 To: 'Lucene Users List' Subject: RE: Lucene beginner Daniel, Thank you very much for replying.

Something like 'java org.apache.lucene.demo.IndexHTML [-create] [-index index]root_directory'. You need lucene and lucene-demo jars in your classpath. If needed, you can use -cp to provide them (java -cp lucene-demos-1.2-rc3.jar;lucene-1.2-rc3.jar org.apache.lucene.demo.IndexHTML ) What's exactly the problem you're having? Regarding Ant, it is a Java based build tool (like make) You don't need to use it unless you want to build lucene. If you're using lucene's binary distribution you only have to have lucene's jar in your application classpath.

search similar docs?
Hi, I was thinking of implementing a search for similar documents (like some commercial search engines do) and wondering if anyone has already done something like that with Lucene. I thought of collecting all terms of the selected document (or maybe some subset of them) and then creating a MultiTermQuery containing those terms. Does it make sense? Is there a better way to achieve this? In order to do it, I would have to get all terms of a given document and so far I haven't found an easy way of doing it (I hope there's one ;-). The way I was thinking is to extend FilteredTermEnum but, instead of selecting terms by similarity, select them by docid (for each term, get its termdocs and check for the desired docid). It doesn't look very efficient so if someone could contribute with other ideas or even related experiences I'd appreciate very much.

RE: problems with last patch (obtain write.lock while deleting documents)
Hi Doug, Problem solved, thanks! BTW, is the way I'm doing the deletion the correct one? I reckon I can't use a cached reader, since I have to close it after the deletion to release the write lock. Does it make sense? Regarding writers, is it ok to share a single IndexWriter with multiple writers, i.e., I have one writer adding a document and then I get another request for doc upload. I can't open a new IndexWriter because of the write lock, so I'm using the one already available. After all writers are done, the IndexWriter is closed. Again, thanks a lot (for the fix and, most important, for Lucene) --Daniel -Original Message- From: Doug Cutting [mailto:[EMAIL PROTECTED]] Sent: domingo, 10 de fevereiro de 2002 19:55 To: 'Lucene Users List' Subject: RE: problems with last patch (obtain write.lock while deleting documents) From: Daniel Calvo [mailto:[EMAIL PROTECTED]] I've just updated my version (via CVS) and now I'm having problems with document deletion.

RE: problems with last patch (obtain write.lock while deleting documents)
From: Doug Cutting [mailto:[EMAIL PROTECTED]] It is most effiecient to batch deletions and insertions, i.e., perform a bunch of deletions on a single IndexReader, close it, then perform a bunch of insertions on a single IndexWriter. Usually the IndexReader that you do the deletions on is different than the one other threads are simultaneously using for searching, since if you close a reader while a search is underway it will crash the search. Unfortunately I can't do that in my application. Users are allowed to insert and delete files at any time and changes should be reflected asap.
