Question What are the limitations for uploading large files?
Answer
  • 32-bit PHP build: Files larger than 2GB are not supported.
  • 64-bit PHP build: Files larger than 2GB are supported, but the file size will not be displayed.

For very large files, it's recommended to upload them manually and provide the URL instead of directly uploading them through the web form.

Question Can users search for specific downloads?
Answer Yes, the unified Composr search system allows users to find downloads based on keywords. This includes searching within download titles and descriptions, as well as within the content of certain file types like PDFs, text files, and even some binary formats (providing they are not too large in size).

View

Question Can I add images to my downloads?
Answer Yes, Composr automatically creates a gallery for each download (if the galleries addon is enabled). You can easily add images directly after creating the download or through the download-view screen. The download gallery is displayed within the download-view screen itself.

Question Are there security features to protect downloaded files?
Answer Yes, Composr includes security measures to protect downloads.
  • Protection from hackers: Uploaded files are stored with obscured filenames, preventing direct access and bypassing of the download system. Additionally, an anti-leech feature (when enabled) prevents direct download links from being shared on other websites (this is done by requiring a session ID which is validated against the person / device accessing it and only provided when Composr presents the download links to you on the site).
  • Basic security: Composr will not let anyone upload dangerous scripts (such as PHP files) which can be executed.
  • Rootkit detection: The rootkit detection tool under yourbaseurl/rootkit_detection.php can help scan files for shell scripts and backdoors. Composr's Health Check can also do this regularly. Note this only offers very basic detection and will not work for obfuscated backdoors (you should use antivirus to scan for those).

It is the responsibility of webmasters to run antivirus on their site to regularly scan files uploaded to it. Composr does not include antivirus software or virus scanning.

Question Where are download galleries located, and can I move them?
Answer By default, download galleries (to contain screenshots of a download) are placed under the root gallery. You can move them to a different gallery for better organization. Here's how:

  • Create a new container gallery (e.g., with codename "downloads").
  • Change the "Create download galleries under" configuration option to your new gallery's codename.
  • Use Commandr to move existing galleries to the new location.

Question Can I sell downloads on my Composr site?
Answer Yes, the download system integrates with the points system, allowing you to charge for downloads. This is particularly useful for communities where members create and share content, like game modifications. You can set prices for downloads and creators earn points when users purchase them. Additionally, you can create a subscription-based system by requiring points for downloads, which users can purchase via methods like PayPal.

Question How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer Composr utilizes multiple layers of defense against XSS attacks:
  • HTML Filtering: Configurable levels of filtering prevent malicious script injection.
  • Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded.
  • Input Sanitization: Data is sanitized before being processed to prevent malicious code execution.
  • Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.

Question Why are my searches slow, and how can I improve search speed?
Answer Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions:
  • MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed.
  • Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet.
  • Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.

Question How does the search engine handle different languages?
Answer Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.

View

Question What are quoted phrases and how do they work?
Answer Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.

View

Question How do stop words affect search results?
Answer Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.

Question How can I improve my search results?
Answer Here are some tips for improving search results:
  • Use specific keywords: The more specific your keywords, the better your results.
  • Use boolean operators: Use "+", "-", and quotation marks to refine your search.
  • Optimize content titles and meta keywords: These fields are given priority during search, so make sure they accurately reflect your content.
  • Consider enabling the fast custom index: Especially beneficial for large websites or frequent filtered searches.

Question What is the fast custom index and why should I use it?
Answer The fast custom index is Composr's own search engine, designed to be faster and more efficient than MySQL full-text search, especially for large websites and filtered searches.

Benefits of the fast custom index:
  • Faster filtered searches: Significantly improves search speed when you add filters like category or author.
  • Configurable stop words: Control which common words are ignored during search.
  • Better stemming: More accurately recognizes variations of words (e.g., "like" and "liking").
  • Multilingual support: Indexes content based on different language translations.

Downsides of the fast custom index:
  • Slight lag in indexing new content: New content takes a short time to be indexed.
  • Less accurate ranking: Ranking is based on the most obscure keyword, not a blend of all keywords.
  • Cannot perform blank searches: You must enter at least one keyword.
