1. Go to https://secure.phabricator.com/maniphest/query/advanced/
2. Set "In Any Project" to "Maniphest"
3. Set "Contains Text" to "Duplicat"
4. Execute query
ACTUAL RESULT:
No results found for this query.
EXPECTED RESULT:
12 results when doing the same query for "Duplicate" instead, and "Duplicat" is a substring of "Duplicate", so it "contains that text".
