+Incorrect backslash escaping on keyword wildcard questions {kibana-issue}169709[#169709].
+[%collapsible]
+====
+*Details* +
+Support for wildcard queries in KQL was introduced in 8.5. {kibana-pull}}140629[#140629]
+
+It appears that backslashes are not properly re-escaped when providing them to a wildcard query.
+
+When running a KQL wildcard query for a keyword field that contains backslashes, such as `field: \*\\\*`, they have to be double-escaped to produce the expected results.
+
+
+*Impact* +
+Results for `field: \*\\\*` are not returned.
+
+*Workaround* +
+Double escape the slashes `field: \*\\\\\*`.
