Hello Vinay, If you want to boost on the author field, but not specifically search in it, it must not be listed in qf, but treated as a boost query, using the boost parameter [1], to create a BoostQuery [2]. You can do all sorts of fun things with it because function queries [3] are extremely vers

Hi Roopa, that's clearer now, thanks. I don't think there's any support for feature extraction from children when calculating the feature vector of a parent. It's an interesting feature though. I would love to design and implement such functionality. If you want to do that on your own I recommend

Hi Vinay, you would like to ideally identify the best field for terms or sequences of terms. e.g. "Brian marketing" Brian -> author marketing -> topic If the query is structured, that's easy, you don't even need the edismax to parse it and you can directly build your lucene language query, as you
