There's a bit of an API glitch with Query objects at present. This code shows it off: Xapian::Database("/path/to/db"); Xapian::Enquire enquire(db); // make a simple query Xapian::Query myquery(Xapian::Query::OP_NEAR, phrase, phrase + 2); enquire.set_query(myquery); // Now change the query - this shouldn't affect the query enquire // will run, but it does.

I got some performance issue for document.get_data() and enquire.get_mset(). It costs 35 seconds for matches = enquire.get_mset(0,200), and 3 seconds for iterating all doc in matches to get_data. Is't normal? My index contains 30millions documents. I use python binding to operate xapian. Bellow it's my index structure # value: 0:date, 1:site # data: json message which contains: author,

I can't quite connect the dots on this, perhaps someone can help. I'm simply trying to create an in-memory database comprising a single document, so that I can run a load of queries against it and see if any of them match the new document (this is to enable users to have 'subscriptions' to saved searches and be alerted every time a new item is published that matches their

In current Xapian SVN HEAD, there is a bug in the query parser concerned with the handling of wildcard terms with a "+" prefix. Specifically, a query such as "+foo* bar" will be parsed by the query parser into Xapian::Query("bar") if there are no terms in the database which start "foo". Instead, since the "+" term cannot be matched, I believe

Why there still been rank when using Query::MatchAll() ?

Hi all, We've struck a problem when using remote queries and hoping someone can offer some guidance. I haven't managed to get a C++ reproduction in the test suite, but I have got a demo that fails using Python: import xapian db = xapian.remote_open('localhost', 8100) qp = xapian.QueryParser() qp.set_database(db) query = qp.parse_query('test') enq =

Lately I was reading many articles about using boolean queries for search engine but I haven't seen any complete working demo. Therefore I put together very simple working demo of search engine using boolean query. Feel free to suggest any performance improvement or error while keeping it as simple as possible for understanding. Thanks, -Kevin Duraj http://myhealthcare.com

Hello, With PHP, I try to get spelling corrections but after 2 days of trying I can make it work !!! Here is my < simple > code : <?php require_once( '../global.info.php' ); require_once( 'xapian.class.php' ); require_once( 'xapianencode.func.php' ); // Open the database for searching. try { $database = new XapianDatabase(

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,

i have 300 millions records and my search file like this , i want the newest 10 results that match my query , so i use boolean search and "enquire.set_docid_order(enquire.DESCENDING)" , but this method seems a little slow . when i remove "enquire.set_docid_order(enquire.DESCENDING)" it run much faster . how can i fetch the newest 10 results as fast as possible? search.py

Dear all, I am working on a very simple project, in which I wanna get the title from the document. For instance, this is what I have done so far. ///////////// code? for building the index file ??????? # Load content ??????? content = open(filePath).read() ??????? # Prepare document ??????? document = xapian.Document() ??????? document.set_data(content) ??????? # Store fileName ???????

I'm trying to compact (or at least merge) multiple databases, while stripping search records which are no longer required. Backstory: I've inherited the Cyrus IMAPd xapian-based search code from Greg Banks when he left Opera. One of the unfinished parts was removing expunged emails from the search database. We moved from having a single search database to supporting multiple

Please keep replies on the mailing list — more people can help (and benefit) that way :) So OP_NEAR looks for its terms close to each other (hence "near"). The window is how far away they can be. Probably the easiest way to play with this is using the NEAR syntax in the query parser. So if you had a plain text document: I am walking, always walking. And index it in a very simple

Hi All, I've installed Xapian and the php module. I've set up a script for use with scriptindex and dbi2omega for getting data from the db into the index easily, the script file is as follows: =============================== id : field=id title : index title: field=title description : index description : truncate=50 field=content ============================= However, when querying

Hello, I have found that the use of sort_by_value very slow. 16800 result, return to the previous 10, sorting takes about 25ms. And if you do not sort, returns 10, need only about 0.3ms. How to make the sort faster? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, dear Xapianers! I've been using Xapian in my project recently. The feature "single writer, multiple reader" is one of my favorite, but currently I can't make it work. My goal is to add more documents to the database increamentally, while the Xapian search process is not stopped. I followed "quickstartindex.cc" and "quickstartsearch.cc" on

I've traced a memory leak to a statement which assigns the values from an MSetItem to a dictionary which is then appended to a list in python. We're running python 2.7.3, xapian-core 1.2.15 and xapian-bindings 1.2.15. I've provided an example which reproduces the behavior below. The example prints the PID and has a few statements waiting for input to make observing the behavior easier.
