The Greek script-language in Patrologia has many diacritics which makes the search complicated if someone is not familiar with language.
To simplify the search, we can use the operator [char] to force the system expand the enclosed character to its various versions.
1) e.g. the word ἐλεημοσυνῶν can be searched by using a word construction such as [ε]λεημοσυν[ω]ν.
2) e.g. the construction [ν]αρσ[η]ς is expanded and the system searches for Ναρσὴς, ναρσῆς, Ναρσῆς, etc.
I hope the examples above will be of help to the user.
