Lucene-based search (i.e. Elasticsearch, CloudSearch, etc.) strikes me as overly complex from a dev's perspective. The indexing and search processes don't seem to have enough sensible defaults and that's to speak nothing of cluster configuration and management, memory issues, etc.<p>In general, there's too much of a requirement to understand Lucene's implementation details in order to use it effectively, and I'm just not sure why the process of building a search feature needs to be so difficult.
