The currencies sample file provides 162 currency codes (ISO 4217 current and some not current) and some additional commercially used codes,  with synonyms of currency name and currency sign, so that a search for 100 EUR will find 100 euro or 100 €.


The currencies sample also includes full width currency sign variants for the Dollar, Cent, Pound, Yuan (Yen) and Won.


It should be noted that by default dtSearch does not index currency symbols, to be able to index and search currency symbols it is necessary to edit the alphabet file. The editor built into dtSearch Desktop controls the processing of characters in the range from 33 to 127 only, the dollar sign ($, character code 36) can be made searchable by selecting the Character type ‘Letter’ instead of the default ‘Space’; characters above 127 are processed according to the Unicode specification and dtSearch does not treat other symbols as searchable characters, however it is possible to manually edit the alphabet file ( to make additional Unicode characters searchable, an easier and faster method is to use the Alphabet file Editor in User Thesaurus Plus.


Note, the WordNet thesaurus built into dtSearch Desktop has no entry for euro, but does have entries for dollar, pound, drachma, dirham and others but contains no symbols or ISO codes.


According to the European Union's Publication Office, in English, Irish, Latvian and Maltese texts, the ISO 4217 code is followed by a fixed space and the amount:  a sum of EUR 30; In Bulgarian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Lithuanian, Polish, Portuguese, Romanian, Slovak, Slovene, Spanish and Swedish the order is reversed; the amount is followed by a fixed space and the ISO 4217 code:  une somme de 30 EUR


The above should be taken with a pinch of salt, since individuals within each country do not necessarily write in that format, to ensure a search for EUR 100 also finds 100 EUR you should search using EUR w/1 100 (i.e. “EUR within one word of 100”).
