Question Can I filter my search results?
Answer Yes, you can filter your search results by:
  • Content type: Choose to search specific content types like news, forum posts, or Comcode pages.
  • Author/Submitter: Search for content submitted by a specific member.
  • Date: Limit your search to content submitted within a specific time frame.
  • Category (for certain content types): Narrow down your search to specific categories within a content type.
Question 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".
Question How do I search my Composr website?
Answer 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.
Question How do I mark correct answers in a quiz?
Answer 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.
Question What is the input syntax for quiz questions?
Answer 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].
Question 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.
Question How can I analyze quiz results effectively?
Answer 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.
Question What are Quiz Sets and how can I use them?
Answer 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.
Question How does scoring work for quizzes with different question types?
Answer
  • Multiple-choice and short answer questions: These are automatically marked based on your defined correct answers.
  • Long answer questions: These require manual marking, resulting in a percentage range being displayed to the user until you assess their response.
  • Unmarked questions: These questions are collected but don't contribute to the overall score, allowing you to include optional or non-scored elements.
Question Can I reward users for completing quizzes?
Answer Yes, you can reward users with points for successfully passing a test. This incentivizes participation and encourages users to engage with your content.

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 What are the different types of security alerts in Composr?
Answer Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include:
  • DODGY_GET_HACK: Suspicious URLs with potentially harmful characters.
  • EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions.
  • SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious.
  • DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files.
  • BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts.
  • SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction.

You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).
Question What are some tips for secure website maintenance?
Answer
  • Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer.
  • Secure Email: Enable SSL for IMAP and POP3 email protocols.
  • Strong Passwords: Use unique and complex passwords for different services.
  • Secure Computers: Keep your own devices patched and secure.
  • Maintenance Password: Remove the maintenance password from _config.php when not in use.

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.
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.
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.
