+*Modifiers* refer to any prefixes (first elements of compound queries)
+that are neither operators nor fields.
+
+``(infix`` *atom* ``)``
+    Interpret *atom* as an infix notmuch query (see

+    phrase fields. Most commonly used in the ``thread`` field.
+
+``(regex`` *atom* ``)`` ``(rx`` *atom* ``)``
+    Interpret *atom* as a POSIX.2 regular expression (see
+    :manpage:`regex(7)`). This applies in term fields and a subset [#not-phrase]_ of
+    phrase fields (see :any:`field-table`).
+
+``(starts-with`` *subword* ``)``
+    Matches any term starting with *subword*.  This applies in either
+    phrase or term :any:`fields <fields>`, or outside of fields [#not-body]_. Note that
+    a ``starts-with`` query cannot be part of a phrase. The
+    atom ``*`` is a synonym for ``(starts-with "")``.
