Hi, all: I have wrote a demo patch for Backend for Lucene format indexes, Lucene version is 3.6.2. http://lucene.apache.org/core/3_6_2/fileformats.html Now, this demo patch just support the basic features in Lucene. Compound File(.cfs/.cfe)?term vector(.tvx/.tvd/.tvf) delete document(.del) are not supported, skip list in .fdx is not supported too example/quest.cc is used to test this demo.

Hi, guys, I wrote a patch for ticket #467<http://trac.xapian.org/ticket/467>(Add standard ExpandDecider subclass to restrict to terms with a particular prefix). A new ExpandDecider class is added in expanddecider.cc/h, which delete all unprefix terms I am a newbiee to open source contribution, please let me know if this patch is work. Patch is here(generate by svn diff):

We noticed, when indexing a Word 2007 document, that two words in adjacent paragraphs got melded together in the Xapian database. For example: To find the document containing these two paragraphs... ...you would search for "containingthese". I fixed it locally by adding a "dump.append(" ");" just before the return in process_text() in myhtmlparse.cc. Thought

All, I'm having some issues compiling omega. Here are the particulars I'm on win7, using cygwin 4.9.2 64 bit.

If you don't provide an implementation of wdf_upper_bound(), the default is to use the collection frequency of the term, so provided that information is available in the lucene files, the lack of wdf_upper_bound information

As Olly has already pointed out the 2012 branch is not merged. I think there are some compilation errors in the branch. The code in branch is better refactored. The Ranker and FeatureManager classes are well defined and implemented. Parth.

Yes - TfIdfWeight doesn't ever use the document length (at least with the normalisations currently

It sounds similar (especially if document and field boosts aren't in use), though some places may rely on

I would really like to try out the features in the patch above. But I can't ever seem to get the resulting omindex.cc to "make". I tried updating to rev 10801 from the SVN then run /bootstrap but then I seem to get errors compiling everything when I try and do "make" (I'm using ubuntu 8.10). So I thought I'd try an apply the patch to the latest stable version

Hi all. I want to iterate over all the documents in my database. my $pi = $db->postlist_begin(""); while ("$pi" =~ qr/END/) { my $oldid = $pi->get_docid; $pi++; #... } That used to work with Search::Xapian in perl version 1.2, but now with xapian-bindings-1.4.4 it does not seem to.

Hello :-) How can the default omega URL be prettified? http://<host_ID>/cgi-bin/omega is working fine, giving us all omega's default CGI parameters. Now we want multiple databases which could be accessed using http://<host_ID>/cgi-bin/omega?DB=<index_ID> but this is starting to get messy. It will get messier when we start to customise templates with

Hi list, Is there a function in R to calculate the omega squared (an estimate of the dependent variance accounted for by the independent variable in the population for a fixed effects model), or does anyone have some code to let me calculate this fairly easy out of aov() or anova() output?

Hi everybody, I am trying to index a big collection of webpages (~15GB) with Omega but cannot index them due the meta tag. Is there some way I can still index them? Kind regards, Merlijn

hi people, I am a newbie to R and I would appreciate it very much if someone can help me. I am used to use SPSS so I don?t have experience with writing a script. I have a questionnaire (questions 1-12) and I would like to use the omega reliability. Question 1-8 is factor 1 and question 9-12 factor 2. How can I write the scripit? Can someone help me???
