• Enter a list of allowed file extensions without dots, separated by semicolons. If you leave the setting empty, the search works for all of the available file types.

If you wish to search one of the unsupported file types, you need to:

• Implement a custom search text extractor
  – OR –
• Use the SQL attachment search

Enabling indexing for page attachments

The attachment search is a part of the functionality of standard Page indexes. The attachment search is NOT available for Pages crawler type indexes, which directly index the HTML output of pages.

To set up the attachment search for your website:

1. Open the Smart search application.
2. Create or edit a Page search index.
3. When defining the search content on the Indexed content tab, check Include attachment content for the index's allowed content.
4. Click Save.
5. Switch to the General tab and Rebuild the index.

While building the page index, the smart search processes the allowed pages, extracts the text of any attachment files and includes it in the content of the index (along with the other page data). When users perform a search using the index, the system returns results for pages whose attachments match the search expression.

Configuring the attachment search

You can adjust how the system indexes attachment files by adding keys to the appSettings section of your application's web.config file.

Limiting the maximum size of indexed files

Indexing of very large files can be resource intensive and have a negative impact on your website's performance. To prevent the system from indexing files larger than a certain size, add the CMSSearchMaxAttachmentSize key:

They key sets the maximum allowed file size in kB. The search ignores page attachments whose size exceeds the value.

Indexing of XML content

When indexing the content of XML files, the search does NOT include the following content by default:

• Comments
• The values of tag attributes

You can enable indexing for such content by adding the following web.config keys:

Enabling character encoding detection for text files

By default, the search can read text files (txt and csv) that use the following character encoding:

• UTF-8⁠ (opens in a new tab)
• The default Windows encoding (the operating system's current ANSI code page)

If you encounter problems when indexing text files with a different encoding type, you can enable automatic encoding detection:

The system then attempts to detect the encoding type for each file, and use the correct option when reading the content during the indexing process.
