First and foremost the Treefinder is a search screen/window GUI that can be auto generated from data objects. So if you have a data object for books, people, toasters, or whatever you can automatically get a screen or window to search for specific books, people, toasters, or whatever with out paying a developer to write a specific screen/window for each one.

The Treefinder generates a search/query object (I_TemplateParams) that contains all of the search/query information entered by the user. This object is fed to the TemplateParserEngine along with the specific template for books, people, toasters, or whatever and you get a query that you can send to your data storage/retreival system (SQL database, EJB Server). The I_TemplateParams, TemplateParserEngine are part of the Adligo XMLT
open source project. The only thing the developers have to do is
generate one template per data object (about a one-two hour task) instead of a custom screen/window for each search (several day task).

In addition to automating the search screen/window the Treefinder gives the user the ability to enter N criteria for each search qualifier. OK, that probably sounds like Greek. For instance if the search screen were pertaining to books the search qualifiers would be things like author, title, publisher, dates published, binding, illustrator, exc...

The user would be able to enter N items for any of these. For instance if the user was looking for a book but didn't know how to spell the authors name, he/she could enter several names Feynman, Freeman, Fimen, Feiman exc. Also the user could enter several date ranges for the dates published for instance between 1/1/1976 and 1/1/1981 or anytime after 1/1/1990. This very power full search capability is just not included in most search screens/windows because the search criteria is entered into a fixed panel with one text box for author, and perhaps a start date end
date for date published.

The Treefinder has similar capabilities for number ranges and uniquely identified criteria (like states, or users).
