After researching some, I have a question in regards to double based attributes.
In the lucene docs, it appears that to speed up searching against double values, it is recommended to convert the value to a more sortable especially if negative numbers are used. The docs recommend using [url]
http://svn.apache.org/viewvc/incubator/ ... rev=382610
[/url] to convert to a sortable value.
I looked at the built-in DoubleBridge and it doesn't use this function.
My questions are:
- is the built-in DoubleBridge adequate for searching/sorting?
- or should I create a SortableDoubleBridge that utilizes the Lucene recommended approach?
Has any one else used double based values in the searching? which implementation was used?
Hopefully I made my point clear.
