The search appliance supports document previews for the following formats:
Document previews are not available for .doc, .pdf and .ppt files in zip files. The document preview module generates document preview images. When you enable the document preview module and configure a front end to show document previews, a magnifying glass icon appears next to search results in supported formats. When a user hovers the mouse over the icon, a floating window shows either the preview image or one of the following preview generation status messages:
If the preview generation is completed but the image cannot be shown, one of the following messages appears:
When a user selects a preview image, she can also page through and enlarge the document preview. If the icon does not appear next to a search result, a preview request has not been sent to the document preview module yet or the document preview module timed out while constructing the preview. Also, document previews are not shown when the "cache" or "text version" link is not available for a search result. Enabling the Document Preview ModuleThe document preview module is disabled by default. To enable the document preview module, click Enable. After you enable it, you can show document previews in a front end. Document previews are only generated during crawl time after you have enabled the document preview module.

Also, the size of document previews might affect search appliance performance. By using the Serve > Document Preview Module page, you can change Image resolution (lower resolution requires less disk space). To change document preview module setting:
Changing the Maximum Pages to PreviewBy default, the search appliance caches five pages to preview for each document. Because document preview images can be large and use significant disk space, you can improve performance by lowering the maximum number of pages to preview. To change the maximum pages to preview for each document:
Showing Previews for Indexed Documents from Databases or Feed Data SourcesTo show document previews for indexed doc, docx, ppt, pptx, or pdf from databases or feed data sources, perform the following tasks:
