Thanks for your reply. Appreciate your effort, but I'm not sure if I fully understand the gain. Having data in JSON would still require it to be converted into Lucene Query at the end which takes space & CPU effort, right? Or are you saying that having query serialized into a structured data blob (JSON in this case) makes it somehow easier to convert it into Lucene Query? I only thought about Java serialization because: - it's rather close to the in-object format - the mechanism is rather stable and is an established standard in Java/JVM - Lucene Queries seem to implement java.io.Serializable (haven't done a thorough check but looks good on the surface) - other conversions (e.g. using Xtream) are either slow or require custom annotations. I personally don't see how would Lucene/Solr include them in their core classes. Anyway, it would still be interesting to hear if anyone could elaborate on query parsing complexity. m.
