To quickly find your files & emails, a search engine must create and maintain an index. An index is like a database of all keywords found on your computer. First, CDS searches documents, emails, attachments and multimedia files that are saved on your computer's hard drive. Then, it will scan and extract the files content to create the index. To maintain the index up to date, CDS use real-time indexation features and automatic updates. The index contains multiple informations, such as:
- File name, folder, location on your computer.
- Metadata: Title, Date, Author, etc.
- Content Text (for supported file types)
As soon as your hard drive is completely indexed, CDS will find your file in less than a second. It associates the keyword saved in the index and those in your files. This allows you to launch advanced queries.
