Databases typically are between 15 and 20 percent of the size of the documents indexed. Because of the compressed indexing algorithms employed, even gigabyte-size searches execute in only a second or two. You can create a brief bank with Isys by changing a single configuration setting. No files need to be moved or reorganized. Then update your Isys database so the change will take effect.
Most Isys users overlook the enormous advantages offered by creating unique file type identifiers.
Batch programs or macros can be used to append the identifier to legacy documents. Thereafter, the resulting unique identifier can be used to limit searches to documents of that type. Despite its array of powerful tools, Isys crossed an ease of use boundry for text retrieval tools even in its DOS days. Prior to Isys, text retrieval engines were either too difficult to use or offered too limited capabilities. However, Isys offers a set of interactive menus and dialogs that require little training or study to be useful.
