Xapian on Android?
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,

Make Xapian accept all characters
Hello everyone, I'm using Xapian at work (PHP bindings) and I have to make it accept '##' as a term to index. We have a layer on top of xapian, but as far as I can tell, Xapian's QueryParser is removing them from the query. So, if I search for just '##' I get an empty query, after Xapian parsed it. I've seen the flags this class accepts, but I can't do what I want

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

xapian query group result by domain?
Hi I know it might not possible, but just want to try my luck. say, for a web search engine backed by xapian.... Is it possible to group the result by domain just like google's [ More results from www.abc.com ], when there are more than 1 results from the same domain? Or, anyone have some work around to do it? Cheers Andrey Kong

Welcome to the "Xapian-discuss" mailing list
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

search without flush.
Hi, Is it possible to perform a search without flushing the index? I've got an application that updates the index every 4 hours but I need to be able to search the new data fairly quickly after the index is updated. The problem revolves around the fact that the update is often much less than 10 000 documents so it isn't being flushed until quite a bit latter. I realise I can do a flush

Does Xapian support retrieval optional?
Hi, I've been using Xapian for a while. But there is a scene I don't know whether supported already. Suppose: 1. Raw query: how to make pizza 2. Parsed query: how AND to AND make AND pizza 3. Documents: d1: how to make pizza at home d2: 3 ways to make pizza d3: make pizza in 4 easy steps Question: 1. During searching process, how to retrieve d2, d3 (although they don't

Prioritizing xapian search results
Hello It is possible somehow to give higher priority to recent document. For example, when adding new document to the database, I will add a term that specifies date of the document. During the search, the date of the document is taken into account in the algorithm that calculates document relevancy. In another project I am working on, I would like to limit number of pages returned from the

Make Xapian accept all characters
Ok, but suppose I have a complex query, something like "(a OR b) AND NOT c OR ##".

xapian bug tracker registration email is not working
I tried to register yesterday, twice with 2 email addresses. The website said it sent me mail, I never got a mail. Someone else, please confirm this is broken. A bug I'd like to file is that I'd like an option to search *word. Currently you can only search word*. The example where I would find this useful is searching for urls and email addresses. For example, I want to find emals from

Xapian-discuss Digest, Vol 88, Issue 9
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

Incremental indexing
Hi all, I am trying to implement an Incremental indexing scheme. The problem is that usually the modified documents are large but the modifications are limited. Ideally, I would like to reindex only the modified parts of these documents. If I am not mistaken, xapian cannot do that. Are there any other approaches? It would be nice if xapian supported something like the SQL "group by".

xapian-config --libs output on Suse 10.1

Xapian::Document and threads
Hi, While investigating very infrequent crashes in the Recoll indexer, I have come to a very basic question: is it safe to pass a copy of a Xapian::Document from thread to thread (multiple threads queue documents, other thread updates the index) ? I don't seem to get directly into trouble while doing this, but I don't see anything either in the RefCntr implementation which would

Xapian 1.4.3 "Db block overwritten - are there multiple writers?"
Hi, I have a user reporting the following error during recoll indexing: flush() failed: Db block overwritten - are there multiple writers? "flush() failed" is from recoll, the rest is, I think the text of the Xapian exception. This is with Xapian 1.4.3 on Linux (I asked for more details, should be coming). I don't think that I've ever seen this error, and I also
