We upgraded yesterday from 4.5.8 to 4.6.5 (with Drupal 7.38). We have a number of custom fields for Individuals which are type multi-select (child's grade in school, marital status, etc.). When we search on those fields from the Advanced search screen, the search yields no results. However, if I create the same search in Search Builder, I get results.
Search Builder example (this is the only search criteria):
Individual > Marriage:Marital Status > = > Widow/Widower
I get 16 results.
If I build that same search in Advanced search, I get 0 results.
I turned on CIVICRM_DEBUG_LOG_QUERY per this post: How can I tell what the query that is executing when I do an Advanced Search looks like?. But, not knowing exactly what I was looking for in the log file, I can't tell what is amiss in the Adv Search.
