ZyIndex 5.21 vs. DTSearch
4.0 Software ShootoutTopLawfirm.com, approx. January 10 2000 by Aaron
Describes the author's experience testing two full-text search engines on
a pleadings directory of 250 documents and 2.5 MB. Both programs had fast
indexing and retrieval and many search features such as Boolean queries, natural
language queries, stemming and similarity. The Author found dtSearch
more intuitive, with more helpful tools for indexing and display on the search
results, but limited documentation. ZyIndex was
more difficult to install, and includes separate indexing and query applications.
It has powerful and easy-to-use hypertext linking tools and annotations.

Describes the whole line of dtSearch products. The dtSearch Index manager
can recognize many current and legacy file formats. The search engine itself
offers Boolean, natural-language, stemming, synonyms and fuzzy matching, and
a thesaurus. APIs are available for Visual Basic, ActiveX, C, C++, and Java.
Praises the documentation for detailed explanations of parameters and examples.
The spider has limited controls, mainly for depth of search. The Web Search
engine uses the same internal code, and displays results quickly. Converting
to HTML for Web viewing is slow.
