Re: Numeric fields and payload

: is it possible to store (text) payload to numeric fields (class 
: solr.TrieDoubleField)?  My goal is to store measure units to numeric 
: features - e.g. '1.5 cm' - and to use faceted search with these fields. 
: But the field type doesn't allow analyzers to add the payload data. I

I'm not sure if it's possible to add payloads to Trie fields, but even if 
there is i don't think you really want that for your usecase -- i think it 
would make a lot more sense to normalize your units so you do consistent 
sorting, range queries, and faceting on the values regardless of wether 
it's 100cm or 1000mm or 1m.

Peter:

I don't quite get this. Formatting to display is trivial as it's
usually done for just a few docs anyway. You could also
just store the original unaltered value and add an additional
"normalized" field.

Hoss,  What you suggest may be fine for specific units. But for monetary 
values with formatting it is not realistic. $10,000.00 would require 
formatting the number to display it.  It would be much easier to store the 
string as a payload with the formatted value.
