The "CurrencyField" page has been changed by HossMan: http://wiki.apache.org/solr/CurrencyField?action=diff&rev1=10&rev2=11 Comment: SOLR-4138 notes about ValueSource and currency(...) function price_c:10.00,NOK }}} + Begining with [[Solr4.2]] Currency values can also be used in functions. By default, specifying a !CurrencyField in a function results in values corrisponding to the most granular precision of the defualt currency (eg: for USD, the most granular precision is cents), but there is also a {{{currency()}}} function that can be wrapped arround currency fields to generate values corrisponding to the natural value in either the default currency, or a user specified currency. + + For example, assuming {{{price_c}}} is a !CurrencyField configured with the {{{defaultCurrency}}} of USD, and assume that with the current !ExchangeRateProvider {{{1.00,EUR == 2.00,USD}}}. The table below shows what various functions would return for documents indexed with various currency values in this field + + || Function || 6.54,USD || 10.00,USD || 5.00,EUR || + || price_c || 654 || 1000 || 1000 || + || currency(price_c) || 6.54 || 10.0 || 10.0 || + || currency(price_c,USD) || 6.54 || 10.0 || 10.0 || + || currency(price_c,EUR) || 3.27 || 5.0 || 5.0 || + = Response Format = Solr documents will always yield the currency values they were indexed with, regardless of how they were queried for. For example, a set of documents indexed in USD will yield USD values for its Currency fields regardless if you performed queries in EUR.
