Feature Description

Search cloud messages to help users quickly locate and index related messages based on keywords. Through this API, users can efficiently find specific message content, improving the speed and accuracy of information retrieval.
Note:
This feature is a value-added service and requires you to purchase the cloud search plugin. Please click Purchase.
The cloud message search feature is supported from v3.1.0.
This API is locally limited to 2 calls per second.
Communities, topics, and live broadcast groups do not support cloud message search.
Search messages in all conversations:
If the number of matched messages messageCount > 1, the API returns messageList as []. You can display [${messageCount} relevant records] on the UI. If you want to highlight the matched messages, refer to searching in the specified conversation and highlight the messageList returned by the API.
If the number of matched messages in a conversation = 1, the messageList contains the matched message.

Searching messages in all sessions

Do not specify conversationID, specify keyword search.
Example
// Full text search, specify keyword
// - Search messages containing 'Hello' or 'Where are you'
let promise = chat.searchCloudMessages({
   keywordList: ['Hello', 'Where are you']
});
promise.then(function(imResponse) {
   // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of sessions containing messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Messages that meet the search criteria are grouped by conversation ID and returned by page.
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID); // Conversation ID
      console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
      // If all conversations are searched, the number of messages contained in messageList may have the following two possibilities:
      // - If the number of matching messages in a conversation is greater than 1, messageList is empty, and you can display "messageCount related records" on the UI.
      // - If the number of messages matched in a conversation is equal to 1, messageList is the matched message, and you can display it on the UI and highlight the matched keyword.
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // failed to search for messages
});

Searching for the Messages in the Specified Conversation

Specify conversationID and search by keyword.
Example
// Specify conversation and search by keyword
// - Search for messages in the 'GROUPPublic001' conversation containing 'Hello' or 'Where are you'.
let promise = chat.searchCloudMessages({
   keywordList: ['Hello', 'Where are you'],
   conversationID: 'GROUPPublic001'
});
promise.then(function(imResponse) {
   // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Message results of the current conversation search
   if(searchResultList.length){
       const { conversationID, messageCount, messageList } = searchResultList[0];
       console.log(conversationID); // Conversation ID
       console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
       console.log(messageList); // List of all messages in this conversation that meet search criteria
   }
}).catch(function(imError){
   console.error(imError); // failed to search for messages
});

Searching for a Custom Message

1. When using the createCustomMessage API to create a custom message, you need to put the text to be searched in the description parameter. It supports matching keywords with description.
2. Specify messageTypeList as TencentCloudChat.TYPES.MSG_CUSTOM for classified search, which will search for all custom messages.
Example
// Full text search, specify keyword and message type search
// - Search for messages of type 'custom message' where the description contains 'Hello' or 'Where are you'
let promise = chat.searchCloudMessages({
   keywordList: ['Hello', 'Where are you'],
   messageTypeList: [TencentCloudChat.TYPES.MSG_CUSTOM],
});
promise.then(function(imResponse) {
   // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of sessions containing messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Messages that meet the search criteria are grouped by conversation ID and returned by page.
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID); // Conversation ID
      console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
      // If all conversations are searched, the number of messages contained in messageList may have the following two possibilities:
      // - If the number of matching messages in a conversation is greater than 1, messageList is empty, and you can display "messageCount related records" on the UI.
      // - If the number of messages matched in a conversation is equal to 1, messageList is the matched message, and you can display it on the UI and highlight the matched keyword.
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // failed to search for messages
});

Searching for a Rich Media Message

Rich media messages include file, image, audio, and video messages.
1. For a file message, the filename is usually displayed on the UI. If you pass in the createFileMessage parameter fileName when creating a file message, fileName will be used as the content to be searched for and match the search keyword.
2. For image, voice, and video messages, there is no name like fileName. The UI usually displays a thumbnail or duration, so specifying keywordList for search is invalid.
3. You can specify messageTypeList as TencentCloudChat.TYPES.MSG_IMAGE/TencentCloudChat.TYPES.MSG_AUDIO/TencentCloudChat.TYPES.MSG_VIDEO for classified search, which will search for all specified types of messages.
Example
// Full text search, only specify message sender and message type for search (when specifying sender and message type, the keyword list can be empty)
// - Search for messages sent by 'user1' or 'user2', and the message type is 'image message', 'voice message', or 'file message'
let promise = chat.searchCloudMessages({
   senderUserIDList: ['user1', 'user2'],
   messageTypeList: [
      TencentCloudChat.TYPES.MSG_IMAGE,
      TencentCloudChat.TYPES.MSG_AUDIO,
      TencentCloudChat.TYPES.MSG_FILE
   ],
});
promise.then(function(imResponse) {
 // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of sessions containing messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Messages that meet the search criteria are grouped by conversation ID and returned by page.
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID); // Conversation ID
      console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
      // If all conversations are searched, the number of messages contained in messageList may have the following two possibilities:
      // - If the number of matching messages in a conversation is greater than 1, messageList is empty, and you can display "messageCount related records" on the UI.
      // - If the number of messages matched in a conversation is equal to 1, messageList is the matched message, and you can display it on the UI and highlight the matched keyword.
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // failed to search for messages
});


Searching Geolocation Messages

1. Support matching latitude, longitude, description with keywords.
2. Specify messageTypeList as TencentCloudChat.TYPES.MSG_LOCATION for classified search, which will search for all geolocation messages.
Example
// Full text search, specify keyword and message type search
// - Search for messages of type 'geolocation' where the latitude, longitude, description contains 'Hello' or 'Where are you'
let promise = chat.searchCloudMessages({
   keywordList: ['Hello', 'Where are you'],
   messageTypeList: [TencentCloudChat.TYPES.MSG_LOCATION],
});
promise.then(function(imResponse) {
 // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of sessions containing messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Messages that meet the search criteria are grouped by conversation ID and returned by page.
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID); // Conversation ID
      console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
      // If all conversations are searched, the number of messages contained in messageList may have the following two possibilities:
      // - If the number of matching messages in a conversation is greater than 1, messageList is empty, and you can display "messageCount related records" on the UI.
      // - If the number of messages matched in a conversation is equal to 1, messageList is the matched message, and you can display it on the UI and highlight the matched keyword.
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // failed to search for messages
});

Searching for Merged Messages

1. When using the createMergerMessage API to create a merged message, you need to put the text to be searched in the title or abstractList parameter. It supports matching title and abstractList with keywords.
2. Specify messageTypeList as TencentCloudChat.TYPES.MSG_MERGER for classified search, which will search for all merged messages.
Example
// Full text search, specify keyword and message type search
// - Search for message types marked as ‘Merge Message’, and messages containing ‘hello’ or ‘Where is it?’ in their title or abstractList
let promise = chat.searchCloudMessages({
   keywordList: ['Hello', 'Where are you'],
   messageTypeList: [TencentCloudChat.TYPES.MSG_MERGER],
});
promise.then(function(imResponse) {
 // Successful search message
   const { totalCount, cursor, searchResultList } = imResponse.data;
   console.log(totalCount); // Total number of sessions containing messages that meet the search criteria
   console.log(cursor); // Starting position for the next cloud search, if not present, indicates search results are fully retrieved
   console.log(searchResultList); // Messages that meet the search criteria are grouped by conversation ID and returned by page.
   for (let i = 0; i < searchResultList.length; i++) {
      const searchResultItem = searchResultList[i];
      const { conversationID, messageCount, messageList } = searchResultItem;
      console.log(conversationID); // Conversation ID
      console.log(messageCount); // Total number of messages that meet the criteria in the current conversation
      // If all conversations are searched, the number of messages contained in messageList may have the following two possibilities:
      // - If the number of matching messages in a conversation is greater than 1, messageList is empty, and you can display "messageCount related records" on the UI.
      // - If the number of messages matched in a conversation is equal to 1, messageList is the matched message, and you can display it on the UI and highlight the matched keyword.
      console.log(messageList);
    }
}).catch(function(imError) {
   console.error(imError); // failed to search for messages
});
