Rebuilding Index; Changing Index Cache File Location

After clicking on the “Advanced” button, there you can also click on the “Rebuild” button to re-index. (may take hours, but runs in the background.)

Tech Detail for Programers

Windows Search is a modern search engine. First it index your files by words into a database. So, when you use search, it can quickly show you files that contain that word.

The Windows Search pane is a virtual folder named 〔search-ms:〕 or 〔Search Results〕.

Understand File Formats

In order to do indexing on various type of files such as Word document, spreadsheets, PowerPoint file, html docs, MP3, image files, OutLook data files, IE cache… it need to be able to understand the format. Microsoft's technology for this is called IFilter. It functions as a component. When a IFilter for a particular file format is installed, search can understand the file and extract words from that file or indexing.

Search Database Location

The location of the database by default is at: C:\ProgramData\Microsoft\Search\Data\Applications\Windows.
