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.
What is the difference between natural and boolean searching?
Answer
Natural search is a more relaxed approach where you type in your search terms and Composr tries to find the most relevant results, even if they don't contain all the words. It's like a Google search.
Boolean search requires more precision and uses operators like "+", "-", and quotation marks to define exactly what you're looking for. For example, searching for "+car -maintenance" will only return results that contain the word "car" but not "maintenance".
There are a few ways to search your Composr website:
Using the search bar in the header: This is the simplest way to search. Just type your search term in the box and click the search button.
Using the 'Search' module: This module offers more detailed search options. You can access it via the 'site:search' page-link (usually under About > Search in the default menu).
From the Forum: Click the 'Search' button on the forum or use the contextual search box on the forum member bar. This will search within your current forum or topic.
For questions with predefined answers, you can mark correct answers by adding [*] after the answer. If no answer is marked correct, the question will require manual marking. You can also use the [UNMARKED] tag after a question to exclude it from scoring.
Quiz questions are inputted in blocks, separated by blank lines. The first line is the question, followed by potential answers on subsequent lines. Different question types are indicated by tags after the question, such as [MULTIPLECHOICE], [MULTIMULTIPLE], [LONG], [SHORT], and [SHORT_STRICT].
Can I create complex, multi-screen quiz interfaces in Composr?
Answer
While Composr's built-in quiz system is excellent for standard formats, creating intricate multi-screen quizzes might require custom development using Composr's decision tree framework or other programming tools. This allows for highly customized quiz structures and advanced branching logic.
Composr enables you to export quiz results to a spreadsheet file, facilitating in-depth data analysis. This is especially useful for manually marked questions, identifying competition winners, and processing data for marketing or research purposes.
Quiz Sets are a helpful organizational feature in Composr. By prefixing quiz names with "Example: ", you can group related quizzes together. This allows for combined scoring and percentage calculations, particularly beneficial for multi-part questionnaires or tests.
The forum base URL should be a URL prefix to your forums without a script name. For example, http://forums.example.com is correct, while http://forums.example.com/index.php is incorrect. You can fix this using the config_editor.php script and then clear the Comcode page cache.
Most Composr resources with commenting enabled create comment topics in the configured comment forum. If the forum uses BBCode, Comcode features not supported by BBCode may not display correctly. Moderate comments from the forum as you would any other topic.
It's not easy to switch forums after installing Composr. The member and usergroup IDs referenced by Composr would lose their association. Check the "Importing data into Composr" tutorial for more information on this.
Conversr is Composr's built-in forum system. It offers seamless integration, allowing you to use Comcode for forum posts, a unified Admin Zone, shared themes and templates, and innovative features like Private Topics and in-post whispers. Using a third-party forum can be clunky and may lead to maintenance headaches.
Composr supports several forum drivers, including Invision Board, phpBB, myBB, vBulletin, Burning Board, and Simple Machine Forum. If your forum is not listed, professional developers can add support. Composr also provides converters for migrating from these forums to its own forum system, Conversr.
What are the PHP requirements for running Composr?
Answer
Composr requires PHP 7.2 or higher, but versions not officially supported by PHP developers are discouraged. The maximum tested version is PHP 8.3.
Required PHP extensions:
GD2 (gd) with PNG and JPEG support
MySQL extension (mysqli or pdo_mysql)
XML extension (xml)
Multibyte String (mbstring)
cURL extension (curl)
JSON support (usually available by default)
Sodium (libsodium)
ZIP extension (zip) if ZIP file support is needed
Additional recommendations:
posix extension for permission checks
zlib extension for faster upgrades, compressed backups, and page compression
ctype extension for slightly faster performance
IMAP extension (imap) for managing newsletter bounces
OpenSSL extension (openssl) for encrypted CPFs, DKIM, and SSL certificate expiry checks
Pspell (pspell) or Enchant (enchant) extensions for spell checking
Ensure the following PHP settings are configured:
File upload size limit of at least 5MB (or higher as needed)
Maximum execution time of at least 30 seconds
Memory limit of at least 128MB
The installer will warn you if any critical functions have been disabled via disable_functions or other PHP modifications. Avoid web hosts that heavily restrict standard PHP functionality.
To uninstall Composr, access the uninstall.php file in your web browser, enter your administrator password, and follow the prompts to remove the database data. Afterward, you can safely delete the Composr installation directory.
What are the recommended web hosting options for Composr?
Answer
Choosing a web host is crucial. Avoid the cheapest options and look for hosts with recent positive reviews and minimal credible complaints. Ensure they meet Composr's requirements, including adequate disk space, no restrictive file size limits, and support for required PHP extensions.
Composr is compatible with various hosting control panels like Plesk and cPanel, and works on Windows, Linux, or Mac OS servers.
Yes, you can install Composr on a Windows desktop using software packages like WampServer, XAMPP, EasyPHP, or ampps for simplified setup. Alternatively, you can manually install Apache, PHP, and MySQL, following the instructions provided in the respective documentation. Remember to configure file permissions appropriately and ensure the webserver isn't accessible from outside your network.
