+## How come my query does not list all the emails on the file system?
+
+You may have emails that have some of the [exclude
+tags](https://notmuchmail.org/doc/latest/man1/notmuch-search.html#cmdoption-search-exclude)
+
+Notmuch can be configured to exclude some tags while searching. You
+can list excluded tags with
+
+ $ notmuch config get search.exclude_tags
+ deleted
+
+To verify this is the reason of the discrepancy, add the excluded tags
+explicitly to your query. If the problematic query is
+
+ $ notmuch search --output=files -- folder:inbox
+
+Try
+
+ $ notmuch search --output=files -- folder:inbox tag:deleted
+
+You can also temporarily turn of the excluded tags feature with `--exclude`.
+
+ $ notmuch search --output=files --exclude=false -- folder:inbox
+
