Dear CLucene users/developers, in the comparable-storage branch, I have implemented a template class ComparableTools to extend NumberTools with the possibility of combining multiple numerical values into one field. The NumberTools functionality is mimicked by ComparableTools<int64_t>, but through ComparableTools<std::pair<first_type,second_type> >, multiple numbers can be combined while keeping the ordering behavior. This can be used to implement use cases like dates (std::pair<std::pair<int64_t,int64_t>,int64_t> with first.first being the year, first.second the month and second the day of the month), but is not limited to that.
Thoughts: * provide specializations for smaller or unsigned integer types, storing them more efficiently * provide support for boost::fusion types to allow more convenient usage of large n-tuples Through the generic mapping of the pure ordering trait for n-tuples into CLucene, I also hope to gain some insights on the mapping of other mathematical traits into CLucene, for example to allow GIS querying. As always, comments are highly appreciated. Best regards, Isidor ------------------------------------------------------------------------------ Come build with us!
