In AnQiCMS multilingual site,containcan the filter correctly judge keywords of different languages?

AnQiCMS as a feature-rich enterprise-level content management system, its powerful multilingual support capabilities allow content operators to easily reach a global audience.However, in the actual content management and display, we often need to perform keyword detection or filtering.containFilter can accurately identify keywords? Today, let's delve into this issue.

containFilter: A direct text matching tool

First, let's take a look back atcontainFilter basic function. According to the AnQiCMS documentation,containFilter is a tool used to determine whether a keyword exists in the target data. It supports multiple data types, including:

  • String:Check if a string contains a specified substring.
  • Array (slice):Determine if an array contains a keywordExact matchelement.
  • English map or struct:Check if its key name or field name matches the keyword:Exact match.

containThe filter will return a boolean value (TrueorFalse），表明匹配结果。例如，如果我们使用{"欢迎使用安企CMS（AnQiCMS）"|contain:"CMS"}}, the result will beTrue，因为它在字符串中找到了”CMS”。

需要特别强调的是，contain过滤器进行的是字面意义上的匹配It does not have any semantic analysis capability and will not automatically translate the keywords or target content you provide. It simply compares whether the character sequences are consistent.

AnQiCMS's multilingual content mechanism

AnQiCMS multilingual support allows us to create and manage independent content for different language versions. This means that an English article and a Chinese article may be two independent content entities in AnQiCMS, or they may have different language fields under the same content entity (for example,Title_enandTitle_zh）。同时，AnQiCMS还提供了语言包（通过tr标签调用），用于翻译界面上的固定文本，确保用户界面的本地化。

When a multilingual site is accessed, AnQiCMS will load or render the corresponding language content based on the current language environment. Therefore, in the template, whether it is the document title, content description, or tag list, they are ultimately presented tocontainFiltering processes are all specific texts under the language environment.

containFiltering performance under multilingual environments

UnderstoodcontainThe literal matching features of the filter and the multi-language content mechanism of AnQiCMS allow us to clearly answer the core question:containThe filter can correctly identify keywords in different languages, but this depends onwhether the language of the keywords matches the actual display language of the target content.

Let's illustrate this with a few scenarios:

  1. Content is consistent with keywords language:

    • If the current site is in English, the title of a document is "Welcome to AnQiCMS", you use{{archive.Title|contain:"Welcome"}}The filter will returnTrue.
    • If the current site is in Chinese, the title of a document is "Welcome to Anqi CMS", you use{{archive.Title|contain:"欢迎"}}, the filter will also returnTrue. In this case,containThe filter can 'correctly' judge, because it found a consistent character sequence.

  2. The content does not match the keyword language (direct match):

    • Assuming the current site is in English, the document title is still 'Welcome to AnQiCMS'. If you accidentally use Chinese keywords{{archive.Title|contain:"欢迎"}}, the filter will returnFalse。Because the English title does not have the Chinese word "welcome".
    • Conversely, if the Chinese title "Welcome to Anqi CMS" contains English keywords{{archive.Title|contain:"Welcome"}}, it will also return.False。\nHere it is necessary to clarify,containThe filter will not attempt to translate 'Welcome' to '欢迎' and then perform the match. It will only compare directly according to the character sequence you provide.

  3. Applied to tag or category list:

    • If your document tag list is displayed in Chinese site:["电子产品", "手机", "智能家居"]then use{{tags|contain:"手机"}}it will returnTrue.
    • 但如果您的目的是在英文站点搜索这些内容，而标签列表也未进行英文翻译（或翻译后存储在其他字段），直接使用 English{{tags|contain:"Mobile"}}it will returnFalseBecause there is no English word "Mobile" in the list.

The core conclusion is: containThe filter itself is language-neutral. It does not have language understanding or translation capabilities. It only performs literal matching, i.e., checking the keywords you provide.Character sequenceWhether it exists in the target contentActual character sequence.

Actual application and operation suggestions

Understanding in the multilingual content operation of AnQiCMScontainThe working principle of the filter is crucial.

  • Keyword precise matching:When you use it on a multilingual site:containThe filter should ensure that the keywords you provide match the current display language of the target content. If you wish to search for English keywords in English content and Chinese keywords in Chinese content, thencontainThe filter will be efficient and reliable.
  • Limitations of cross-language keyword detection: containThe filter cannot achieve true cross-language keyword detection (for example, searching for 'car' can find content containing '汽车' or 'voiture'). If your business scenario requires this advanced feature, you may need to consider more complex solutions, such as:
    • Multilingual content field:Set an independent language field for each content item (such asTitle_en,Title_zh) and then apply the corresponding language field in the template for different language environments.containFilters and corresponding language keywords.
    • Backend logic enhancement:When publishing content or indexing, it is advisable to pre-translate keywords into all target languages and store them, or to make use of the powerful language processing capabilities of external search engines for advanced searches.

In summary, AnQiCMS'scontainFilter is a powerful and direct string/set matching tool.In a multilingual environment, as long as we make it clear that it only performs literal matching and ensure that the input keywords match the actual language of the target content, it can effectively help us filter and display content.
