Subject [jira] [Commented] (SOLR-2202) Money FieldType
Date Sat, 28 Jan 2012 10:11:10 GMT


Jan Høydahl commented on SOLR-2202:

This is great! I'll see if I can test it a bit more next week, and see if I spot any bugs
or improvements.

This will be a great addition.
It would be kind of nice to demo the fieldType in all the prices in the exampledocs. Then
we need to change fieldType of the "price" field to MoneyType etc. Only problem then is that
we cannot demo price range facets in /browse as we do now.

Do anyone know what it takes to make range facets work with this field type?

And a minor one: Why do we call the class MoneyType? All the other fields are called XxxField
(except for the LatLonType and PointType). Is this intentional. To me it would sound even
better with "CurrencyField" :)

> Provides support for monetary values to Solr/Lucene with query-time currency conversion.
The following features are supported:
> - Point queries
> - Range quries
> - Sorting
> - Currency parsing by either currency code or symbol.
> - Symmetric & Asymmetric exchange rates. (Asymmetric exchange rates are useful if
there are fees associated with exchanging the currency.)
> At indexing time, money fields can be indexed in a native currency. For example, if a
product on an e-commerce site is listed in Euros, indexing the price field as "1000,EUR" will
index it appropriately. By altering the currency.xml file, the sorting and querying against
Solr can take into account fluctuations in currency exchange rates without having to re-index
the documents.
> The new "money" field type is a polyfield which indexes two fields, one which contains
the amount of the value and another which contains the currency code or symbol. The currency
metadata (names, symbols, codes, and exchange rates) are expected to be in an xml file which
is pointed to by the field type declaration in the schema.xml.
> The current patch is factored such that Money utility functions and configuration metadata
lie in Lucene (see MoneyUtil and CurrencyConfig), while the MoneyType and MoneyValueSource
lie in Solr. This was meant to mirror the work being done on the spacial field types.
> This patch will be getting used to power the international search capabilities of the
search engine at Etsy.
