 The boolean prefix searches (see Boolean and Probabilistic Prefixes in the man
 page), such as tag: or path: searches, need an exact match.
 
+## How do I search for folders or paths with spaces?
+
+The spaces in the names must be escaped. For example if you use bash or zsh,
+you can search for messages with tag `foo` in folder `INBOX/folder with spaces`
+with this query:
+
+        $ notmuch search tag:foo 'folder:"INBOX/folder with spaces"'

 ## How do I search for the `List-Id:` header?
 
 Currently there is no way to search for `List-Id:`. As a workaround, try using a

 order in which the duplicates were received. This is a more general problem than
 just `List-Id:`, and once this has been resolved, adding `List-Id:` indexing is
 trivial.
+
+## Can I use notmuch with grsec?
+
+Sure! It works out of the box. If you have TPE enabled (trusted path execution),
+make sure the user is executing the script belongs to the
+`kernel.grsecurity.tpe_gid` (in debian this is grsec-tpe).
+This is required in order to run the `pre-new` and `post-new` hooks.
+
+## Can I tag threads?
+
+No. Tagging is message based.
+
+It is possible, however, to make tags propagate to all messages in a thread
+using a little bit of scripting in the [[post-new
+hook|manpages/notmuch-hooks-5]]. For example, to add the muted tag to all
+messages in threads that have at least one message with the muted tag:
+
+        THREAD_TAGS="muted"
+        for tag in "$THREAD_TAGS"; do
+                notmuch tag +$tag $(notmuch search --output=threads tag:$tag)
+        done
+
+You can add other tags to `THREAD_TAGS` as needed. Note that this is one way
+only; you need to explicitly remove the tag from all the messages in a thread to
+stop it from propagating again.
