Uniform Title vs. Subject Heading

What should one do when one wants a subject access to a work for which only an established uniform title exists
(e.g., Blessing of the sun) but no corresponding subject heading?  Some materials do have both a uniform title and a corresponding subject heading (u.t.=Siddur,  s.h.=Siddurim; u.t.=Haggadah, s.h.=Haggadot, etc.).

Until subject headings be established for several liturgical headings similar to this one, where  no subject heading has previously been established to correspond with the established uniform title, one should use a combination of subject headings.  For example, for works consisting of the liturgy of "Blessing of the sun" (without commentary),  use the following combination of subject headings:

1.  Sun--Religious aspects--Judaism.
2.  Benediction--Judaism--Texts.
3.  Judaism--Liturgy--Texts.
