Hello, I came across the file *omega.cc* which is in directory* xapain-application/omega/* In this file , atoi is used in *Percentage Relevance cutoff *(293 line no) as Percentage lies between 0-100 their is no need to modify atoi . But do we need to check for error's ? Second Implementation is in *collapsing* (301) in which we collapse set of document under a key,range of this key has not

Dear, guys: I am a beginner of Xapian, when reading the documents, I encountered follow questions. (1) I see the Xapian::Document has a method void add_value (Xapian::valueno valueno, const std::string &value) What's the purpose of this method? Document will related to the terms, but what's the purpose of this? (2) add_posting method will add term to a documents. void add_posting (const std::string &tname, Xapian::termpos tpos, Xapian::termcount...

Xapian::valueno is an unsigned type, so you effectively can't pass a negative value in (if you do it'll be converted to a large positive value and would work if used consistently). Thoughts?

Folks, Is it possible to query a document value (doc.set_value(i, val)) as part of the Omega query. I know how to do it from code. Is there a query markup to use for Omega? ...Thanks, ...Ken

Hello all. I have a problem with collapsing by a key in a compound database. I have 2 databases (e.g. clients and client branches), both of them have the same attribute (with the same valueno), `client_id'. What I need is to search in both these databases and collapse results by `client_id' to get client IDs (set_collapse_key is used with collapse_max=1). The problem is that I receive 2 equal `client_id' values in the MSet (one per database?). Is it possible to get unique...

...n the right incantation to expose my MatchDecider class.

...order depending on the distance... My information to calcul distance is in values in the document. How I can access document values from Weight to be able to add some sum_extra weight ?? I just tried to create a function in Weight that look like: Xapian::weight get_sumextra(std::map<Xapian::valueno, std::string> values) const; to calculate an extra weight from my documents values... But now I going deeper and deeper in the code to make this functions working... Is it the good way to do this or there is an easier way ?? Thanks a lot Regards. Eric

Hi, Sorry to follow up on an old thread, but I am wondering if there has been any work done on, or interest in, increasing the maximum document id beyond a 32bit limit?

Thanks that helped :). I am still trying to cover add_value some more though since I seem to not understand it totally. I guess it is because I am used to Lucene and Sphinx and Solr and it appears that Xapian seems to attach the type of value stored more on add_value. Like for example I am still a bit confused on how slotno actually works and what it actually is. I think the main thing is

Hi everybody, I want to read the name of the arguments of fucntion IR LLVM, I have the following function define: define void @vecadd(i32, float* nocapture readonly, float* nocapture readonly, float* nocapture) local_unnamed_addr #0 { As we see, the argument has no name, if we look at call function in main function we see the arguments name (a, b and c): call void @vecadd(i32 10, float*
