Last year my colleague Tom Mortimer talked about indexing security information within an open source enterprise search application, and we're happy to announce more details of the project. Our client is an international radio supplier, who had considered both closed source products and search appliances, but chose open source for greater flexibility and the much lower cost of scaling...Continue reading

Networking in a great city for enterprise search
Cambridge, U.K. has a long history of hosting search experts and businesses. Back in the 1980s two firms arose - Cambridge CD Publishing, founded by Martin Porter and John Snyder grew into Muscat, and Cambridge Neurodynamics became Autonomy. We believe Smartlogic still have a sm...Continue reading
Chalk and cheese – the difficulty of analysing open source options
David Fishman of Lucid Imagination has blogged on how open source search is treated by the analyst community (you can even use his links to get hold of some of the reports mentioned for the usual price of your contact details). We can add to his list a report from the Real Story Group<...Continue reading
Legal search is broken – can it be fixed with open source taxonomies?
I spent yesterday afternoon at the International Society for Knowledge Organisation's Legal KnowHow event, a series of talks on legal knowledge and how it is managed. The audience was a mixture of lawyers, legal information managers, vendors and academics, and the talks came from those who are planning legal knowledge systems or implementing them. I also particularly enjoyed hearing from <...Continue reading
Open source search engines and programming languages
So you're writing a search-related application in your favourite language, and you've decided to choose an open source search engine to power it. So far, so good - but how are the two going to communicate? Let's look at two engines, Xapian and Lucene, and compare how this might be done. Lucene is written in Java, Xapian in C/C++ - so if you're using those languages respectively, everything should be relatively simple - j...Continue reading

The current (and first!) version is 0.1, which can be checked out from the flaxcode repository. This version supports named fields for inde...Continue reading
Packaged solutions and customisability, the Python way
With any large scale software installation, there is going to be some customisation and tweaking necessary, and enterprise search systems are no exception. Whatever features are packaged with a system, some of those you need will be missing and some won't be used at all. It's rare to see a situation where the search engine can just be installed straight out of the box. Our Flax system is based on the Xapian core, which has a set of bindings to various differe...Continue reading
Xapian 1.2.0 arrives
Xapian 1.2.0, the first of a new 'stable' release series, was announced a few weeks ago and we've just uploaded pre-built binaries for Windows and associated build files. You can find them on our Xapian downloads page. This version features a new, faster, more compact database format and enhanced backwards compatibility with existing databases; a built-in replication system (so in a distributed system you only need to propagate the changes to a Xap...Continue reading
