Xapian omega windows

You can grab the source for this guide from github , which contains the example code in each language in the code subdirectory , and also the data files listed below in the data subdirectory.

The first dataset is the first objects taken from museum catalogue data released by the Science Museum. We downloaded this data from their API site, but this has since shut down. The second dataset we have curated ourselves from information on Wikipedia about the 50 US States.

Both are provided as gzipped CSV files. As we describe how to use Xapian, and show how to use it with practical code examples, we provide the commands needed to compile if necessary and run the code described.

The issue is that the documentation on how to use the build files is poor. I'm going to have to spend the time to build the doc on what I did to get it working and the pitfalls 32bit v 64bit Here's the article I posted about how to do this: codeproject.

Cody Caughlan Cody Caughlan I read that The learning curve is steep to say the least. Let us know how it goes. I revisited it and compiled it with vcpp and it worked again, lack of doc made this way more difficult than it needed to be and then realized I didn't need to compile it the bindings had what was needed. Then the downloadable bindings and the ones I built are 32bit I punted and am looking at lucene.

I did get it though Can I suggest then that you post on the Xapian-discuss list, as they are usually very responsive there Sign up or log in Sign up using Google.

And, I can't guarantee that there won't be any issues since you're going to get a lot of compiler warnings about lost precision. You're going to need Visual Studio. Go install it. Get the build files one zip and source code three gzip-ed archives from the Flax hosting site.

Under this directory, you should have three directories, one for xapian-bindings-x. Unzip the Win32 build scripts from Flax into the xapian-code directory it should unzip into a win32 subdirectory. Open the zlib. You'll likely be asked to convert the project, say Yes To All. Select the LIB Release project from the dropdown and build it. Select the DLL Release project from the dropdown and build it. Create an include folder in the zlib directory.

Copy the zlib source to that include directory. Create a lib directory in the zlib directory. In this directory, make a copy of the zlib. Edit the following line:.

Run "nmake". If everything goes according to plan, after a while, and a lot of compiler warnings about possible loss of data, it should be done compiling.

There's a "bug" in the coding for the compilation of the bindings for x Run "set libpath", and if the result ends in a semicolon ; , then you need to reset the libpath in order to compile the bindings. This should compile the bindings. This should compile the omega component of Xapian. The Xapian features page is a bit of a bait and switch. So for the vast majority of the documents you'll be interested in parsing, Omega will require other third party applications -- which may or may not be available for your use on the Windows environment.

It also appears that Omega will call these external applications and rear their output to parse the text of the document. While this isn't necessarily a bad way to accomplish the task of extracting text out of documents, it can potentially become a point of failure that will be extremely difficult to track down because there will be little logging if any of the errors that occur when calling external applications. In the C world, Lucene. NET is the most common search "engine" used.

It has its own issues no recent official releases, poor documentation, performance concerns over large data sets since it's running in managed code, etc. It does not offer a tool such as Omega, so you will be responsible for extracting the data from documents via IFilter or the same external programs as Omega.
