: My 'inspiration' for the ord method was actually the Solr 1.4 Enterprise : Search server book. Page 126 has a section 'using reciprocals and rord : with dates'. You should let those guys know what's up!
1) Although it's not 100% obvious, those examples in the book use the "DateField" type -- and ord() should still work for those. If you are using TrieDateField then things work differently. 2) David and EricP are regulars on the solr-user list, so rest assured they already know. 3) There is a wiki page with an Addendum section they wrote to cover things that changed in Solr prior to the 1.4 release but after they went to press. Trie fields are mentioned, as is the new ms() function, but i don't see anything explicitly addressing the snag you hit ... yet. It is a wiki afterall, so you can feel free to add things as you find them. -Hoss
