Searching for exact match with hash symbol

@pete31 would program this more elegantly, I’m sure, but this should provide you with an input dialogue:

-- Show search results for search term containing non-indexed character(s)

tell application id "DNtp"
		set theRecords to selected records
		if theRecords = {} then error "Please select some groups"
		set theResults to {}
		set dAnswer to "#Action"
		set userEntry to display dialog ¬
			"Enter the non-indexed character you wish to find" default answer dAnswer with title "Find a non-indexed character"
		set theSearchTerm to text returned of userEntry
		repeat with thisRecord in theRecords
			set thisRecord_Type to (type of thisRecord) as string
			if thisRecord_Type is in {"group", "«constant ****DTgr»"} then
				set thisRecord_UUID to uuid of thisRecord
				set theResults to theResults & (contents of database of thisRecord whose plain text contains theSearchTerm and uuid of parents contains thisRecord_UUID)
			end if
		end repeat
		set theWindow to open window for record (root of viewer window 1) with force
		set search results of theWindow to theResults
	on error error_message number error_number
		if the error_number is not -128 then display alert "DEVONthink" message error_message as warning
	end try
end tell
