Understanding Indexing

Learn what indexing is and how it works

When you connect a folder, Wissly automatically indexes the documents inside it. Let’s look at this process in more detail.

What Is Indexing?

Indexing is the process of reading document contents and organizing them into a quickly searchable form — similar to how an index is built at the back of a book.

Wissly’s Indexing Process

1. Text Extraction

   Opens document files and extracts text.

2. OCR Processing

   For scanned documents or images, recognizes text using OCR.

3. AI Transformation

   Transforms extracted text into a format the AI can understand.

4. Index Storage

   Stores the transformed data securely on the server.

Sync and Automatic Updates

Indexing doesn’t happen just once. Wissly continuously monitors connected folders.

Change Type	Wissly Action
File Added	Automatically indexes new documents
File Modified	Updates the index for changed documents
File Deleted	Removes from the index

This process happens automatically in the background, so there’s no need to manually click “refresh.”

Checking Indexing Status

You can check the indexing status of each folder in the Folder Management screen.

Status	Meaning
