Koji Sekiguchi reopened SOLR-2202:
----------------------------------
Reopening, as CurrencyField depends on the definition "tlong" in schema.xml and
I don't think it is a good idea.
If tlong fieldType is not there, I got NPE.
{code:title=CurrencyField.java}
protected static final String FIELD_TYPE_CURRENCY = "string";
protected static final String FIELD_TYPE_AMOUNT_RAW = "tlong";
{code}

> 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.
