I would like to be able to search for a specific Case Type as well as a Case End Date within this case type. To give an example, say I have a record that contains both Case A (which ended January 2018) and Case B (which ended December 2018). Right now, the advanced search is returning this record if I search for "Case Type A" AND "Case End Date December 2018." However, I would like the search to NOT return this record, as the end date (December 2018) is not affiliated with Case Type A. Is there a way for me to conduct such a search? I'm using CiviCRM 5.13.4.
Try the case summary report, which might not be visible by default. Go to Administer - CiviReport - Create New Report From Template. Then pick the Case Summary report. Then on the filters tab set your filters.
