similar to: Xapian setup.

Hi, all guys: I invented a new ranking algorithm inspired by the theory of spread activation and probabilistic model, which can find the latent semantic relationship between docs and terms, and I took one afternoon to implement this idea, which is almost linear time, and the testing result shows that the speed of this algorithm is much faster than the famous Latent Semantic Analysis

Hello guys, I have an weight value which is calculated by some factor and i need to add the weight with the relevancy value of a result and sort it with that value is that possible in xapian.

hi! alls i have read an article about comments on Lucene. http://www.jroller.com/melix/entry/why_lucene_isn_t_that i have more understanding about Lucene through this article,especially its disadvantage or limitation. then i would like to question that are there similar disadvantages to xapian? any advice would be appreciated. baijl

Hi, I am currently trying to benchmark a multithreaded xapian implementation on a chameleon baremetal instance written in C++. My workload is a 3 Gig wikipedia xml dump consisting of ~286 file of different sizes. My results are showing me that indexing on xapian is an order of magnitude faster than my lucene and lucene plusplus implementations. This is a result that I did not expect. Just want to

I found the solution o this using SEQ_RANGE_ARRAY_ADD(&RESULT->DEFINITE_UIDS, UID); Now, I can see in the logs that several times, the dovecot calls the fts_backend_xapian_update_set_mailbox with box == NULL.

hi, i use xapian to index a txt file, it's size is 268M. i take each line as a document, and each line has two field like 13445511 | 111115151. the recored size is 10000000. the XAPIAN_FLUSH_THRESHOLD set 1000000. it takes 1026544ms to index the file, it is more slower than lucene. The lucene speed is about 40000 records per second. code: try { Xapian::WritableDatabase

Hi all, I've been a Lucene user for the past year, but lately, with most of my project moving to Python, I really love Xapian's clean python binding. I can't seem to see how to boost a query term using Xapian's query syntax. In Lucene, there is "hello^4 world^.2" to boost "hello" and suppress "world". However, digging through Xapian's

Hi, I have been trying to get fts solr to work for a while. Keep getting the error below(was wondering if this was schema related?) root at mail:/var/log# doveadm index -u user at domain.net inbox doveadm(thai at sicl.net): Error: fts_solr: Indexing failed: Server Error Below is from the apache solr output log:- Appreciate if someone can confirm the cause of this error. Thanks Kevin

Hi Guys, I just wanted to take a moment to give some positive feedback regarding my experiences with Xapian recently. I've been doing a fair amount of research into search engines recently, as we have some fairly specific requirements with what we're attempting to do with them. Long story short, after a few weeks of playing around with just about everything under the sun (or at least,

additionally, my logic is that the backend stores one databalse per mailox in /xapian-indexes (in the "root" dir of the user), the name od the database is the GUID of the mailbox For INBOX, that works perfectly, and database is properly createdm and backed starts indexing all emails For other folder, somehow, the process can not access that (root) folder. Am I missing something ?

I somehow fixed the folder issue. (seems some unix rights after too many tests) Getting back on the "fts_results" structure: I am trying: I_ARRAY_INIT(&(RESULT->DEFINITE_UIDS),R->SIZE); I_ARRAY_INIT(&(RESULT->MAYBE_UIDS),0); uint32_t uid; for(i=0;i<r->size;i++) { try {

I am writing a java based client that would be executed from windows that will use libvirt. 1.

Hi, I've a problem to integrate xapian in my web application. I've developed the code for index e for search the documents published through my application. The app is developed in PHP. I've created a file that contain some function for search (called simpleSearch and advSearch). The problem is that if i run the code through the IDE (Zend for Eclipse) as PHP script it work correctly,

Hi all, I'm (still) need(ing) something like Solr[1] to Xapian, to make it I have 2 options, extend xapian-tcpsrv or re-implement ftss project[2], the problem of ftss is that it is 5 years old, and there's lots of changes into Xapian library (and also libc), what is the best way to implement a Solr-like server to Xapian? Did you done some progress Philip Neustrom? [1] -

I think this is a shining example of how well Xapian works with large document collections. I was just discussing this with my colleagues here and one of the issues that came up is that we'd love Xapian to become really lot more popular but have found that the documentation's a bit difficult to get into, as is the API. So I was wondering: do you have any thoughts on improving this and

Hello all, I am Mohd Azeem. I want to contribute in Xapian but I am a newbie here. I wonder if anyone could help me in getting started with Xapian. I have some basic knowledge of IR and implemented TF*IDF and PageRank schemes, and also implemented Inverted Index and Web-Crawler. regards, Azeem -------------- next part -------------- An HTML attachment was scrubbed...

Hello, It's probably quite troll-risky to put a title like this, but did anyone take the trouble to compare Lucene to Xapian and make a list of differences? As I told the list at the end of last year, I'm going to have to integrate an indexing/search engine in the coming weeks or months. It will be integrated to Dokeos, an open-source e-learning application in PHP, and at the moment we

Not really, as the steps outlined by Timo would not get done.
