Webpage tags

Tag overview

This feature provides tags for sites and URL paths. Tags are applied to URLs using regular expression (regex) patterns to help users understand and filter search results.

Tag list

Enum values and examples

The coverage of various tags changes continuously as indexed sites and paths are updated. Tag coverage for links is currently about 89%.

genre (content type)

isUgc (is UGC)

ugcType (UGC type)

The ugcType tag is only meaningful when isUgc is true.

industry (industry classification)

isListPage (is list page)

Usage and recommendations

The UnifiedSearch API returns tags within the tags object for each pageItem in the response. The API does not support filtering by tags in the request, so you must filter the results you receive.

Sample request

curl  -X POST https://cloud-iqs.aliyuncs.com/search/unified \
--header "Authorization: Bearer $API_KEY" \
--header "Content-Type: application/json" \
--data '{
  "query": "Hangzhou weather",
  "engineType": "LiteAdvanced",
  "contents": {
    "mainText": true,
    "markdownText":false,
    "summary": false,
    "rerankScore": true
  }
}'

Response

{
    "requestId": "c7ca543a-6fc3-4563-a39a-720ffb134978",
    "pageItems": [
        {
            "title": "Weather forecast for Hangzhou, Zhejiang on March 15, 2026",
            "link": "https://tianqi.moji.com/forecast10/china/zhejiang/hangzhou",
            ......
            "tags": {
                "genre": "Official",
                "isUgc": "false",
                "industry": "General",
                "isListPage": "false",
            }
        },
        ....
    ]
}

Recommendations

1. Use tag exclusion whenever possible. This helps prevent empty result sets that can occur when filtering for a small number of included tags.

2. Combine multiple tags for exclusion to achieve more precise filtering.

3. Identify tag combinations that consistently produce undesirable results for your use case, and add them to your blocklist.

Use cases

1. Automotive: Exclude low-authority and UGC sites

• Query: Difference between the three Li Auto L7 models

• Number of results: 20

• Filter code:

  def should_exclude(tags: dict) -> bool:                                                                                                                       
        """

        A result is excluded if any of the following conditions are met:
        1. tags.ugcType is one of ("StructuredQA", "NoteShare", "ForumPost")
        2. tags.isUgc is "true" and tags.genre is "ForumUgc"
        """
        exclude_ugc_types = ("StructuredQA", "NoteShare", "ForumPost")
  
        ugc_type = tags.get("ugcType", "")
        genre = tags.get("genre", "")
        is_ugc = tags.get("isUgc", "")
  
        # Condition 1: ugcType is in the exclusion list
        if ugc_type in exclude_ugc_types:
            return True
  
        # Condition 2: Content is UGC and the genre is ForumUgc
        if is_ugc == "true" and genre == "ForumUgc":
