search for: xappy

I want to be able to do searches with FLAG_PARTIAL and some without. Most searches without but with the PARTIAL for an autocomplete widget. I'm using xappy and I can't find where to send the flag when I build up the query. The docs talk of setting up the database with or without FLAG_PARTIAL but that's probably not what I want. Peter

I'm planning to add multiple-database support for searches to my "Xappy" python wrapper (more on this wrapper later, but for now, see http://code.google.com/p/xappy for details). This is reasonably straightforward, because Xapian supports this nicely: except that "Xappy" generates a "fieldname->prefix" mapping automatically. The prefi...

Hello, I have a corpus that I have indexed with xapian/xappy and I would now like to generate a corpus-specific list of stopwords. (This is a technical corpus, so a typical stopword list wouldn't be helpful.) My first thought was to ask the xapian database for a list of terms followed by their frequency. My intuition is that I could probably bring toget...

Hello, I'm trying to index some blog stuff through python bindings. I'd like to know how to add some informations (url, title, date, and so on) so that I can reach them through a xapian.Enquire object.. I believe it's something to be set in xapian.TermGenerator(), but... I can't manage to find which function. I'm waiting for something like : xtermgen.add_meta('url',

what is the fastest way to fetch results which are sorted by timestamp ? i want to use xapian as my search engine , use add_boolean_term(something) and add_value(0,sortable_serialise(get_timestamp())) to a doc. search through enquire.set_weighting_scheme(xapian.BoolWeight()) and enquire.set_sort_by_value(0,True) to ensure that the results are sorted by the timestamp. This method is ok , but

Hi, The xapian-extras supports image similarity.( http://xapian.wordpress.com/2009/03/11/xappy-now-supports-image-similarity-searching/ ) I complie xapian-extras and xapian-extras-bindings with python. import xapian import xapian.imgseek doc = xapian.Document() imgsig = xapian.imgseek.ImgSig.register_Image(JPEG_PATH) imgterms = xapian.imgseek.ImgTerms('A', 300) imgterms.AddTerms(do...

I came across this benchmark between Xapian & Solr: http://www.anur.ag/blog/2009/03/xapian-and-solr/ According to the benchmark, a doc set that took Solr 34 min to index took Xapian 7 hours. Solr's index is also much smaller - 2.5GB to Xapian's 8.9GB. I'm new to Xapian. Just wondering if results like these are typical? Is indexing speed & size a known issue in Xapian? Or is
