search for: get_eset

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

My code is not on Github. I am using the tarball as of now.

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

I read up the code for the proxy,internal and iterator classes of Eset and Mset to get a feel of how those sets work.I then traced the working of Enquire::get_eset( ) (understood it well other than how a Termlist tree is built ) and Enquire::get_mset( ) (didn't understand this one completely,got lost during Multimatch::get_mset()) .I also read up the code for Xapian::Weight (both proxy and internal class) and the codes of BM25 and TradWeight classes .

Since search result diversification is its naive form performed by expanding query with different context and adding document from different context in final rank-list, thereby catering to all context of query.

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:

Hi, all: I am not quite clear about the internal process of query in xapian, is there any differences between querying in a single database and a multiple database, if both of them have the same amount of data? For example, the single database has n documents, which is equal to the total documents' count of the databases in the multiple database ? What are the differences

Hi, I'm using xapian with c# and mono and i'm having a segfault in get_weight. When i print the index variable, the value is clearly too high. I think something write over it. Do you have any idea on how i could trace the beginning of the segmentation fault ? Thanks, -- Yann

...many problems that 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 li...
