update: we have what we need for now, thanks.
We’re building a research tool for reporters, a semantic search engine, an index of primary source documents with our grant from the Knight Foundation. DocumentCloud will be free and open source software.
We also need an expert-level PostgreSQL consultant to sit down with us and review and refine our architecture plans. We’re looking someone with plenty of experience working with sharded Postgres installations, someone skilled at tuning Postgres for full text searches over very large datasets (potentially approaching hundreds of thousands of documents) and well versed in best practices for deploying Postgres on EC2.
