First-up, thanks to Logos for including the Liturgy fields in the Sermon Info. It will certainly improve searchability of sermons in the future.
However, it would make it much more useful if those fields would provide a drop-down (or maybe a pop-up similar to when you start entering a Bible verse) which would allow a user to consistently enter the Liturgical Day, Season or Year.
Without this feature I expect to see inconsistencies from sermon-to-sermon or year-to-year, which may limit the effectiveness of searches in the future. E.g. for the coming Sunday, November 29th, I could enter "First Sunday of Advent" (which matches the description in the RCL) or "1st Sunday of Advent" or "Advent 1", (or even enter a typo).
I imagine Logos already has all these labels internally (e.g. the RCL seems to be structured in this way), so it would (hopefully) just be a matter of making them available to the user.
Thanks for your consideration.
