Brad: 1) if you haven't already figured this out, i would suggest emailin the java-user mailing list. It's got a bigger collection of users who are familiar with the internals of the Lucnee-Java API (that's the level it seems like you are having difficulty at)
2) Maybe you mentioned your sorting algorithm in a previous thread, but i'm not remembering it -- it's possibly this is an XY problem, if you describe the algorithm you need (or show us the code for your Comparable impl) we might be able to suggest an efficient way to do this with out any custom code in Solr... http://people.apache.org/~hossman/#xyproblem : I'm trying to get my (overly complex and strange) product IDs sorting properly in Solr. : : Approaches I've tried so far, that I've given up on for various reasons: : --Normalizing/padding the IDs so they naturally sort alphabetically/alphanumerically. : --Splitting the ID into multiple Solr fields and sending a longer, multi-field "sort" argument in the GET request. : --(both of those approaches do work "most of the time", but aren't quite perfect) : : However, in another project, I already have a <code>Comparble</code> class defined in Java that represents a ProductID and does sort them correctly every time. It's not yet in lucene/solr, though. So I'm trying to make a FieldType plugin for Solr that uses the existing ProductID class/datatype. : : I need some help extending the lucene FieldComparator class. I don't know much about the rest of the solr / lucene codebase, so I'm fumbling around a bit, especially with the required setNextReader() method. setNextReader() looks like it checks the FieldCache to see if this value is there already, otherwise grabs a bunch of documents from the index. I think I should call some form of FieldCache.getCustom() for this, but FieldCache.getCustom() itself accepts a comparator as an argument, and is marked as "@deprecated Please implement FieldComparatorSource directly, instead" ... but isn't that what I'm doing? : : So, I'm just a bit confused. Any help? Specifically, any help implementing a setNextReader() method in a customComparator? : : (solr 1.4.1 / lucene 2.9.3) : : Thanks, : Brad : : : : -Hoss -- http://lucenerevolution.org/ ...
