I would like to use the mod() function in a query to for example fetch every 10th or 100th matching document, or to return documents that return a certain result from the mod() function for a numeric field. I know this question has come up in the past and I have seen answers that suggest using Solr’s function query parsing to implement it. But I am using Lucene 6.1.0 without Solr and would like to implement this with just lucene-core and lucene-queries. Probably a quick answer but I can’t seem to find the class(es) in Lucene that implements this, guessing FunctionQuery / ValueSource which is now in the lucene-queries module? If anyone could point me to a sample implementation that would be very helpful.
