similar to: How to locate the query term in search results?

Hello, I'm having a litle issue with Xapian-1.0.6 with php bindings under php5 when trying to add a new document it throws: Fatal error: Uncaught exception 'Exception' with message 'DatabaseCorruptError: Failed to unlink /var/lib/xapian/trade.ar/termlist.baseA: No such file or directory' in /usr/share/php5/xapian.php:1140 Stack trace: #0 /usr/share/php5/xapian.php(1140):

Hey guys ,Hi :) I am working on a hack which will allow the user to specify a weighing scheme (along with the parameters , if he does not not want to use the default values) to build the Eset (rather than using the hard coded TradWeight scheme with default k=1 ) as Olly had suggested that we can probably get better terms (a more relevant Eset) for query expansion if we use say something

Hi, I have previously had a problem with getting this error on a get_mset call, and solved it by subclassing XapianEnquire with a backoff-and-retry algorithm (as suggested by this list, many thanks!). However, I now get it intermittently when calling get_data on a XapianDocument. The same solution doesn't seem to be quite as easy in this case, because: 1. The document is not instantiated

I've just noticed that new indexes no longer have position.{DB,baseA,baseB} files, all previous indexes (I roll indexes every week using xapian-compact) have the position files. The index seems to work but it is returning some odd results, for example if I run a query with the phrase "machine learning" it mostly returns documents containing "machine learning" but it also

Hi guys, I'm trying to improve the search results of our collection by tuning the parameters in the BM25 weighting schema. Since our collection includes several databases, such as for pictures, websites, etc., I would like to use different values of the same schema to calculate the weights. Yet, rebuilding each time after the change was done to the head file seems not an optimal approach and

Note: this is rather long and not very important and I don't want to prevent the team from releasing version 1.0, so go on reading only if you have too much free time !!! ;-) 0 is not a valid document ID, never, ever, but I just found a special case in which xapian will create a record and return 0 for the newly created record. In fact, I was "hacking", trying to store metadata

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000);

The way I was thinking of performing reranking with updated weights was to add a class MSetRanker (basically containing a

Folks, Having trouble getting this to work. OMEGA cgi is not reading my stub file properly because it is trying to read it as a directory instead of a file. Is there an easy fix?

Hi, I'm playing around with asterisk 1.6.2.0 and the first try was to replace my now non-functionning 'app-realtime' macro which emulated RealTime with REALTIME_HASH() There is very few documentation on the subject except for this bug report: https://issues.asterisk.org/view.php?id=13651#c94998 However when i try this syntax:

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
