Empty results OMEGA with XAPIAN 1.0.1
Hi, I configured XAPIAN 1.0.1 and OMEGA 1.0.1. on my development machine (first removed the old ones). I recreated my databases (both quartz and flint) and tried to run original queries against the databases created by the new versions. I'm getting empty result sets from OMEGA. If I use the delve tool I actually see that the records are created fine. No log files are written as far as I

setting ValueRangeProcessor at runtime
I want to set a variable number and type of ValueRangeProcessors at run time based on a configuration file. But I seem to be running into (what I think is) a C++ scope issue. I tried just a simple test to see if I could add 5 VPs in a loop. Xapian::QueryParser qparser; Xapian::Query query; int vp = 0; while(vp < 5) { Xapian::StringValueRangeProcessor sproc(vp++);

Stemmer Modifications
I'm using Xapian as a search back-end on a website. My client has certain search terms that the stemmer does not stem in a way they would like. For example "continuity" stems to "continu", which produces undesirable results in their application. Is there a way to override the stemming of certain words in a way that is compatible with the indexing stemmer and the query

understanding stemming and synonyms
I am working with version 1.2.7 and want to use stemming and synonyms. I use the perl-bindings and get some problems. First of all: the perl-bindings dont allow the QueryParser a third argument when calling parse_query! So i cannot set a default prefix (which perhaps is the solution to my problem, but later more) i have a simple testcase: 3 documents, every document only has one word:

ferret finds ''tests'' but not ''test''
Hello all, Quick question (possibly!) - I''ve got a few records indexed and doing a search for ''test'' reports in no hits even though I know the word ''tests'' exists in the indexed field. Doing a search for ''tests'' produces a result. I would have thought that ''test'' would match ''tests'' but no such

non-snowball stemmer
Hi! I am going to use non-snowball russian stemmer with Xapian. There is a good one at http://www.aot.ru. I've found that current implementation of Xapian::Stem does not allow it (there is no public interface for Xapian::Stem::Internal). Do you apply patches? Are there any recommendations for writing patches? Regards, Oleg Obolenskiy highpower at mail.ru

Facets with Multiple Values
I'm trying to determine the best way to index facets with multiple values. For example, let's say we have several books and we want an Author facet where one can filter the books by the author. The problem is each book can have multiple authors. Is there a way to index multiple author names into a single value slot for each book? I see there is a Xapian::StringListSerialiser class that

best practices - combining sql database and xapian, size of database?
Newbie-alert: I'm just getting started on a new project involving a full text search requirement, and my initial investigation points to xapian being the way to go. Two questions: - eventually I'll most likely be indexing towards 50 million documents - is this reasonable to expect or attempt with xapian? - each of my documents come with a set of attributes. These are easily stored

Bitsize project: Krovetz Stemmer
Hello xapian devs, I had shown interest in writing a krovetz stemmer for xapian and spoke to James Aylett about it. Since it was hard to code the stemmer in snowball, I came up with a C++ implementation of the stemmer. But since it is a dictionary based stemmer, im having problems on deciding how to create the dictionary. I did check out some of the implementations of the Krovetz stemmer online

Add an example to the community page and contribute more code
Hi guys.I've finished an example indexer which acts like a grep replacement for a file.It indexes each line containing a proper noun in a given text file.The line containing the proper noun will be displayed upon searching for that noun.I would like to add it to the community code examples.I'm planning to write more examples which demonstrate some advanced features of Xapian along similar
