+# The challenge in searching gender variants with KorAP and DeReKo is that,
+# firstly, some characters used for gender marking, especially punctuation marks,
+# are interpreted and indexed as token boundaries and, secondly, punctuation
+# marks are currently not indexed in KorAP.
+#
+# The former is intentional with regard to a majority of use cases and with
+# regard to the reproducibility maxim (see Diewald/Kupietz/Lüngen 2022).
+# The latter is a shortcoming in KorAP that will be remedied sooner or later
+# and that can be solved provisionally in the meantime with the help of the KorAP API.
+#
+# The following unravelPunctuationGenderCases function, for example, takes the
+# result of a frequencyQuery for two supposedly consecutive tokens and then looks more
+# closely into the KWIC snippets to see which non-indexed strings actually do appear
+# between these tokens and counts the frequencies of the variants that occur.
