I'm sure there are more. Here are the Find A Grave database field names used in PHP queries, via the URL.

GRAVE SEARCH 
GSfn = grave search first name
GSmn = grave search middle name
GSln = grave search last name

GSbyrel =   all, in, before, after                                                        grave search birth year relative to
GSby = grave search birth year 
GSdyrel = all, in, before, after                                                          grave search death year relative to
GSdy = grave search death year
GScntry =0 = grave search country                                          0 = all
GSst = 0  = grave search state                                                 0 = all

GSob = grave search order by
	c = cemetery
	n = name
	d = death
	b = birth
	t = date added to FAG, newest first (t = time?)

GScid = grave search cemetery identification

GSiman = grave search include maiden name
	0 = don't include maiden name		
	1 = include maident name

GSpartial = Grave Search partial last name
	0 = don't include partial last name search
	1 = include partial last name search

df = date filter
	np = no photo
	 p = photo
	1 = 1 day
	7 = 7 days
	30 = 30 days
	90 = 90 days

GSsr = search results
	  1 = show memorials 1 - 40
	41 = show memorials 41 - 80
	81 = show memorials 81 - 120
	121 = show memorials 121 - 160
                  You can put in any number up to the max number of records returned in the query.
	etc.

GSmid= 47363392            = member identification (all records MANAGED by that person)
GSmcid=47363392           = member identification (all records CREATED by that person)
       both turn on partial last name search by default.
GSmpid=47363392           = member photo identification (all records where that person placed a                                                  photo on the memorial (partial last name search doesn't work here)


pt = cemetery name, in text (pt = place text ?) spaces must be shown as %20

If you search for a LastName = 123 (or any 2 or more numbers), you get all records with a blank last name.

If you search for a LastName = 123 (or any 2 or more numbers), with the partial last name block checked, you get all (?) records. Add a FirstName, for instance, George, and it returns all records that have a first name of George!
