Free Webinar: Implementing Solr open source search in a .NET and DBMS environment; Thurs 27 May 13:00 GMT (9a EDT)
I'd like to invite you to tune in to a great talk I saw at Apache Lucene Eurocon (www.lucene-eurocon.org) this past week in Prague by Bo Raun, of Nordjyske Medier. The talk was on how he discovered Solr and introduced it successfully in an IT environment whose strategy otherwise totally rests on Microsoft technologies (and other traditional commercial solutions, like Citrix, VMware, etc). Bo also discusses the contrast between a traditional relational database background and the different development outlook he needed, along with discoveries, surprises, and lessons learned, from which newcomers to Solr from commercial search and DBMS backgrounds might benefit. Today Nordjyske Medier uses Solr for an editorial archive, and for an online yellow page directory, with new plans for Solr technologies in the near future to incorporate advanced search features like geosearch and Solr integration with an ontology engine.

Searching for a strict prefix
Hi, I have a Lucene index that contains source code tags (a tag can be any named source code element - function, class, variable). Each document contains a field with the tag name and some additional information. I'd like to be able to perform strict prefix queries. E.g. if I have a tag named "updateChildren", I'd like to be able to write a query like "updateC*" and get the list of tags that have this prefix (updateChildren being one of them). Is there a way to do this? Please suggest how I should store the field for this purpose - which analyzer to use, whether to keep it stored, etc. Thanks, Shlomy - To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
Implementing Analyzer with Pling Stemmer
Hi guys! for the purpose of my project professor has advised me I should use the PlingStemmer to index the terms obtained from Lucene. http://www.mpi-inf.mpg.de/yago-naga/javatools/doc/javatools/parsers/PlingStemmer.html I see it is new approach and for sure I understand benefits of incorporating it into my project, but building an Analyzer was bit far out of my view of the project, (but what can we do now:)). So I am having problems wrapping my head around how to incorporate the PlingStemmer to build a custom analyzer :/ If someone can help me with advices, links, or someone already had experience with PlingStemmer, I would be very grateful, all help is very very welcome!

RE: Implementing Analyzer with Pling Stemmer
Just look at the source code of PorterStemFilter.java and its corresponding Analyzer in Lucene Java. Simply copy the code and replace the calls to stem a String by the ones from this class. Depending on if your code takes/returns String or char[], you have to modify the code a little bit according to TermAttribute's Javadocs. - Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de > -Original Message- > From: Xaida [mailto:hota.a...@gmail.com] > Sent: Sunday, May 23, 2010 6:11 PM > To: java-user@lucene.apache.org > Subject: Implementing Analyzer with Pling Stemmer > > > Hi guys! > > for the purpose of my project professor has advised me I should use the > PlingStemmer to index the terms obtained from Lucene. > http://www.mpi-inf.mpg.de/yago- > naga/javatools/doc/javatools/parsers/PlingStemmer.html > > I see it is new approach and for sure I understand benefits of incorporating it > into my project, but building an Analyzer was bit far out of my view of the > project, (but what can we do now:)).

About loading lazily
Hi: Can you give me some details about loading lazily? What happens when I load fields lazily? Thanks in advance Luo Lei
Re: About loading lazily
When a field is lazy loaded, the actual value is not retrieved from the server until it is rendered by the UI. This is the same behaviour as the LiveView that ExtGWT currently supports. The difference is that once a value has been retrieved once, LazyLoad will not fetch that value from the server again. LiveView will request the same values over and over again as the user scrolls up and down. - To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
