Searching on value of MMS column, no search result returned

  • Article

Whenever we try to run a search using the terms from our metadata column, no search result returned.

You can try the following below to resolve the issue. There could possibly be two things going on here-

  1. We need to resync the taxonomyHiddenList
  2. Crawl account doesn't have access to the taxonomy hidden list

For the first part-

Please run below script. Change the https://youurl to your site collection url and we should be good to run this!

$site = Get-SPSite https://yoururl

$session = Get-SPTaxonomySession -Site $site

$session.DefaultKeywordsTermStore.ResyncHiddenList($site)

$site.dispose()

For the second part-

You can access Taxonomy hidden list by browsing like this- [site url]/Lists/TaxonomyHiddenList/AllItems.aspx

Add the "Everyone" group to have read permissions to the taxonomy hidden list for the site collection.

If above two still don't resolve the issue then turn up the logging for SharePoint Search category and compare with below flow of events-

In below trace- Crawled property is- ows_taxId_TaxKeyword and it holds data like Investor,Developer,compliance for MMS column Taxkeyword
