Install a Search Client in Slack

This feature is not available in the SearchUnify Cloud Edition.

Find more than just files, channels, and messages on Slack. A new search bot for Slack allows you to search your content sources, including Salesforce, Lithium, and Zendesk, across all the channels of a workspace.


Please talk to SearchUnify if you need a search bot in multiple workspaces. Currently, only one search bot is available for each SearchUnify instance.

Do not confuse the search client with the SearchUnify app on Slack App Directory. The latter is merely a demo. You cannot connect any content source with the app or customize it in any other way.

Installation Overview

Capabilities and Limitations

The ability to search enterprise data repositories inside Slack is a huge advantage. It saves time because there is no tab hopping, no cumbersome login screens, and no digressions involved. Users can run @botname <keyword> during a chat to find results immediately. In the next image, the bot name is "ubermenschen."

Users can also use search operators and filters. The operators work as usual but to invoke a filter, a user has to run the command /filters <keyword>. Filters are limited in two ways: They don’t update when a value is selected and Merge Facets is unavailable to admins.

Nonetheless, admins can still:

  • Set synonyms
  • Define stopwords
  • Use Create Formula to implement access control
  • Apply keyword tuning
  • Boost entire content sources

However, Slack was never designed to be an information retrieval platform. So @botname <keyword> cannot do everything that is possible on a typical search client that you find on websites, Salesforce orgs, and other platforms.

For starters, there is no way to change templates or use Designer because the search is a simple textual command without any GUI interface involved. Then, in the absence of a dedicated search page, analytics data is not available. All this means that the services based on analytics and GUI cannot be accessed. These services include:

  • Tuning: Auto Tuning and Custom Tuning
  • Search Client Settings: Change Summary Preferences, Merge Facets, Auto Suggestions, Advertisements, Page Rating, Language Manager, Similar Search Recommendations and Recent Searches
  • Asset Library
  • NLP Manager, Did You Mean?, Suggestion Removal
  • Knowledge Graph

Besides, search results are capped at 5 for each query.
