dtSearch in the news
- dtSearch Desktop 7.21 was included in a review of Desktop Search products in this month's PC PRO (UK edition). dtSearch Desktop was one of only 2 out of the 10 products reviewed that achieved a 100% accuracy score (12 out of 12). Unfortunately the published tables contained a number of errors; Thunderbird e-mail was shown as not supported, in fact all MBOX e-mail types including Thunderbird are supported by dtSearch. The table also indicated that Firefox is not supported; dtSearch Desktop is not browser based and will work alongside ALL available browsers including Firefox, it does require Internet Explorer to be installed on the machine but does not require it to be the default browser. (See here for dtSearch supported file types)

Use of the language packs with dtSearch substantially improves recall when search expansion using stemming is used. More information and pricing can be found at our Language page. This brings the total stemming languages supported by the Language Packs to 28, which we believe surpasses all other products worldwide. This latest version also has a multilingual installer (English, French, German, Spanish, Dutch).
New dtSearch 7.21 release adds IFilter support!
The new 7.21 range include an adapter to use installed IFilters*. IFilters are components that extract text from documents and are available from many companies, these enable dtSearch end-users and developers to expand the range of document types that can be searched. For example, when you install Microsoft OneNote, an IFilter is installed to enable searching of *.one files.
* Range includes: dtSearch Desktop, dtSearch Network, dtSearch Web, dtSearch Publish, dtSearch Engine. The IFilter adapter works on systems with the Microsoft component query.dll installed. For information on products that include query.dll, see http://support.microsoft.com/dllhelp.

Happy 2005!
Do you know
that 31 July 2005 is the deadline for the new German language spelling reform,
after that date all official publications in Germany must comply with the new
spellings. However, private citizens in German speaking countries can continue
to use the old spellings. If you or your organisation need to search on German
documents you should make sure that the search tool you are using can understand
both old and new spellings. Using dtSearch Engine with the Western European
Language Pack for example will ensure that your application or Internet/Intranet
site can find documents spelled either with a "scharfes s" like this:
'Straße' even if a search query uses a double-s instead like this: 'Strasse'.
Ukraine has a new
President but the languages remain the same. Our Eastern
European Language Pack includes Ukrainian and Russian as well as
8 other languages and will ensure you never miss a document or web page because
you forgot to use the correct word form.
New Language Pack updates
Czech and Slovak are the latest additions to our Language Packs LEP403
(Eastern European) and LEP400 ((Eastern + Western European), more are in the
pipeline for 2005!
