Building and Maintaining Indexes

Overview of the process of creating and updating indexes.

Remarks

dtSearch can search large volumes of text very quickly. It does this by building an index that stores the location of words in your files.

An index is a collection of files, most of which are named index_*.ix, located in a single folder. Each index must have its own directory.

Any index can contain any combination of document formats.
