I am curious about your use case. Was it full text search? Did you get the database in wiki format, which you transformed to text?
The goal of my library is to enable quick data mining on wikipedia. Search is just one use case. As an example, you might want to build a content classifier to automatically categorize web pages into wikipedia categories (like politics, sports, etc). To go about doing this, you would need to parse wiki pages and extract features (like n-grams) for a particular category. The C library transforms plain wiki text to a parsed object, that you can use to extract what information you want. The only advantage is that it does this incredibly fast.
