Passage Search: the Answer to Your User Questions!
Searching for top-ranking documents with Solr is dead-simple: submit your query and Solr will spin its wheels to match your query against documents, score each one and return a ranked list of them. But what if your application requires searching for, say, a paragraph or a sentence? Indexing those as documents is not always possible, as well not very flexible, especially if different users require searching for different-sized portions of the documents.

In this talk I will describe the problem of Passage search, what use cases it addresses, and how it differs from traditional Document search with highlighting. I will also review multiple implementation approaches, all of which can be implemented at the client side, without modifying out-of-the-box Solr code. I will then conclude with evaluation results of each approach.
