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): https://github.com/white127...

Currently ExpandDecider::operator() and MatchDecider::operator() return `int' for no very good reason that I can see. It would be more natural to return `bool', since these classes are making a "yes/no" decision about whether to include a term in an ESet or a document in an MSet. The problem is that th...

Hi List Is there a good way to generate search term suggestions meant for the user to see? I was thinking using the relevance set and expansion set stuff for this, but since these functions return a lot of Z-prefixed stemmed down versions of words, those results are not always suitable to be presented to the user. Cheers Alec

I tried using the simpleexpand.php from http://xapian.org/docs/bindings/php/examples/simpleexpand.php5 I get different results between PHP and the Omega expand (see below), I'd like to have the same functionality in PHP. Could anyone suggest how to do it? Is there an example I could use? Thanks, Frank And got the following results from PHP: Zdefin: weight = 46.963883268652 Zconfigur:

...er the next half of the month, the plan will be to get feature extraction and elkans-kmeans (with triangle inequality) to be working well. As Olly has mentioned in one of his comments on the PR, it wouldn't be ideal to use hard coded criteria for feature selection. Thus using something like an ExpandDecider would certainly be great. I will look into it and make my approach clear as I go ahead. Thanks, Richhiey -------------- next part -------------- An HTML attachment was scrubbed...

I just get the latest version of Xapian 1.2.2 and see that the Java bindings still aren't in a package. Do these work? I am trying to hack them into a package but I can't find where the actual swig -java command is being executed from to add the -package command. Any ideas? -- Jarrod Roberson www.vertigrated.com/blog

Hi All, I would like to take a doc in the xapian DB and find all related documents by relevance e.g. so when you view one document it says "Related entries X Y Z". I'm aware of the "Morelikethis" Lucene plugin that is supposed to do something like this, by generating a query from a document based on term frequency. Has anyone developed a tool to generate a query from a

Hello guys, I was looking forward to participate in GSoc14. I have a decent knowledge about c++ and parsers. I was looking at the idea pages where I found many interesting projects, in which "clustering of search results" interests me the most. I want someone to take me to the right track in understanding the project so that I can think about its implementation. According to me, in this

...t I was not able to resolve : - some methods are documented but do not exist in the wrapper (e.g. empty(), max_size(), swap(), create()...) - some forms of methods use arguments types which are not in the wrapper and should not be documented (e.g : get_mset with a MatchDecider, get_eset with an ExpandDecider, SimpleStopper::__construct() with iterators...) - some methods exist in the wrapper but are not documented. This is everything which is specific to the bindings : http://svn.xapian.org/trunk/xapian-bindings/php/docs/bindings.html?view=co and some which are not documented like (Simple)Stopper::ap...
