Dose Xapian support wildcards (left truncation)? E.g. *ildcard.doc or *.doc or Wild*.doc I read a post from Olly in 2005 that said it wasn't supported yet, I was wonder if there had been any progress or easy work around since. I mainly need when users want to search by the filename extension. Thanks, Frank

I would really like to try out the features in the patch above. But I can't ever seem to get the resulting omindex.cc to "make". I tried updating to rev 10801 from the SVN then run /bootstrap but then I seem to get errors compiling everything when I try and do "make" (I'm using ubuntu 8.10). So I thought I'd try an apply the patch to the latest stable version

Ocassionally when I'm searching using Omega I get: "DatabaseCorruptError: Cannot open tables at consistent revisions" If I click reload it's all ok, is this the database being updated?, is there a way to avoid the message? Frank

Attached is my rather largish omindex.cc patch with ChangeLog. It needs autoreconf to update configure and the Makefiles. Note that unrar is not patent infected, only rar, the compressor. I've put some AC_PATH_PROG checks into configure for all helpers. The patch is not yet complete. 2006-08-18 15:13:32 Reini Urban <reinhard.urban at avl.com> omega-0.9.6b: * omindex.cc: last_mod as

Guys, I was just playing around and added a bit of code to omindex.cc so I could ocr tiff and tif with gocr which seems to work. Here's what it looks like: // Tiff: } else if (startswith(mimetype, "image/tif")) { // Inspired by http://mjr.towers.org.uk/comp/sxw2text string safefile = shell_protect(file); string cmd = "tifftopnm " + safefile + "

Hi all, I recently started with Xen (3.1.0) on my new server running Ubuntu Gutsy (7.10) and I''m experiencing very poor network performance on my domU''s. Since my colo provider offers me a /28 of routed public IPs next to one interconnection IP to their routers, I built a Xen configuration as described in http://www.debian-administration.org/articles/360 (a routed

I'm playing around with a machine that has 2 GB of memory. Indexing about 5GB of data average of 2MB per document. The documents are plain text. I notice the omindex's memory fott print get's biger an bigger then the machine starts to swap and it all slows down to a crawl. In regards to export XAPIAN_FLUSH_THRESHOLD I know the default is 10000 Am I right in saying that for my setup

Greetings, I was curious if the 3.x glusterfs has made any significant write performance headway (especially when dealing with small files). Last time I was testing 2.x, I had to write glusterfs off due to poor performance (previous config/performance-stats can be accessed in list archives if curious). Did anyone notice *dramatic* improvement when switching to 3.x? Thanks, Michael

The problem described in the subject appears NOT to be the case. It's not that simultaneous reads and writes dramatically decrease perf, but that the type of /writes/ being done by this app (bedtools) kills performance. If this was a self-writ app or an infrequently used one, I wouldn't bother writing this up, but bedtools is a fairly popular genomics app and since many installations use

Hi. I am writing a python equivalent of omindex (we are using scriptindex currently - but I wanted to use omindex instead, and extend it to work with our internal file format.. BUT did not want to compile code if possible... so anyway). I have tried to keep the code as close to possible to the omindex native code, but am facing a bit of confusion: what exactly is the reason for omindex to take

I've been working on an R performance academic project for the last couple years which has involved writing an interpreter for R from scratch and a JIT for R vector operations. With the recent comments on Julia, I thought I'd share some thoughts from my experience since they differ substantially from the common speculation on R performance. I went into the project thinking that R would

Hi guys, I've been noticing more and more that antiword has trouble with many word documents. It may look like it's converted a document but leaves out headings and bits of text. I've been looking into getting openoffice to do it in headless mode but still have a way to go before it's stable. I was wondering if anyone else had any luck on this front? One quick fix I have found

Anyone used Flax to search for docx? I'm testing on XP. Installed msxml6.msi and FilterPackx86.exe but Flax dosen't seem to register *.docx as a document type. Is there a way for me to add it in? Thanks, Frank

I was also wondering if someone could tell me how to extract the total number of documents contained in a database via PHP. Thanks, Frank

I tried using the simpleexpand.php from http://xapian.org/docs/bindings/php/examples/simpleexpand.php5 I get different results between PHP and the Omega expand (see below), I'd like to have the same functionality in PHP. Could anyone suggest how to do it? Is there an example I could use? Thanks, Frank And got the following results from PHP: Zdefin: weight = 46.963883268652 Zconfigur:
