Hi,
I love computer science and big data. I would be thrilled to do this project and to give you a simple way of looking through your indexed documents. I build websites on a daily basis, I focus mainly on the server side stuff, though I also do some UI.
I'll build you a small website so you can query your articles and visualize them in a nice way. I've built several e-commerce websites with similar needs, though I've mainly used Postgre's JSONB datatype so I can get the best of both worlds in my apps (relational and NoSQL); I also have experience with Apache Solr, which i believe is a nifty data store.
I already have lots of code and HTML I can reuse, and tons of experience, so I can finish the job very quickly. I assure you a top quality solution, so pick me ;D
P.S. If you also need a way of uploading data to Solr tell me and I'll include it in the website. BTW I'll need to know the general structure of your articles. Please contact me if you have anything else in mind and I'll try my best to implement it.
Cheers!
