I am interviewing candidates for a position developing an application which relies heavily on Lucene. In addition to the usual questions I ask, I’d like to be able to ask one or two Lucene-specific questions that will give me a rough idea of how familiar they are with the library. The problem is that I have no experience with Lucene myself. Any suggestions?

    A couple of questions I would ask:

    • What is the Lucene data structure? (inverted index)
    • How does Lucene computes the relevancy of a document? (vector space model, boolean model)
    • What is a segment? (a portion of the index)
    • How text is being indexed? (analyzers, tokenizers)
    • What is a document? (collection of fields)
    • What is the Lucene query syntax looks like? (boolean query, boost, fuzzy searches)
    • How it differs from a relational database and when would you use one over the other?
