Friends, I would like to hear from anyone who has experience deploying Xapian on Android. I'm new to Xapian, but I know it is used by a couple partners for offline projects on Linux and Windows. Our small nonprofit, WiderNet, provides off-line access to thousands of Web sites for people who lack Internet connectivity (www.widernet.org). Over 2,000 universities, schools, health care sites,

Hi, I'm new to Xapian and wanted to know if it has a specific feature. I want to be able to check the relation between two terms on a page based on how close they are together on the page. I want to use a combination of n-gram based labeling and the "slop" feature found in Elasticsearch. Does Xapian have this/a similar feature? I haven't been able to find any programs that have

I was also wondering if someone could tell me how to extract the total number of documents contained in a database via PHP. Thanks, Frank

I have a bit of code (Python) to delete a number of documents: for f in Flist: xapian_store.delete_document(f.pri_key) in which I am using a unique primary key from an SQL database as the docid for the Xapian database. The problem I have is that some of the documents may not have been created - so I get an error. Now I could just ignore the error (try-recover), but what would be the

Sorry if this is the wrong forum to discuss Search::Xapian issues -- this just seems like the best place.. Anyways, I've been testing out using $db->add_database() when searching, and it seems like the docids I'm getting out of it are incorrect, almost as though they're "double" what they should be (numerically)... the docids that exist should be around 950,000 and

I'm having trouble translating from C++ to perl objects. The TermIterator class looks like to get a set of terms in a document you might have C++ code like: Enquire::TermIterator termIt =enquire->get_matching_terms_begin(id); for(;termIt != enquire->get_matching_terms_end(id);termIt++) { string term = *termIt; } Or something similar. However when I attempt to translate that

Hi, I have callcenter running with v 1.2 with AgentCallbackLogin and now trying to move to 1.4 using the example doc, doc/queues-with-callback-members.txt. From what I understand the basic idea in the example is to 1. Authenticate a caller with VMAuthenticate 2. Get his SIP Channel number 3. Use

Thanks, the Centos 6 repos don't have that rpm and the http://xapian.org/download page seems to only cover the XS bindings, if I am reading this correctly: But I was able to remove the rpm packages and compile and install the core and swig from source.

OK, I'm indexing my data with the scriptindex. I want to be able to restrict the search by the category field. Do I need to do anything to the data itself? Like, literally prefix it with the characters "XC"? Below is my indexor for scriptindex and the my php code... document_id : field=ref unique=Q boolean=Q search_id : field=document_id index=S document_title : field=title

Hello, guys. Q1. now I have load all the docid and its document data into a dictionary for faster loading data instead of calling Xapian::MSetIterator i; i.get_document().get_data(); but I was happened to discover that the dictionaries got by such two method were different: both methods use DB1, DB2 method 1: Xapian::Database db = Xapian::Database(the path of DB1); Xapian::Database db2 =

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
