It seems You are all right, but I don not find the matching values.

===== 8>< =====
\documentclass{ltxdoc}
\usepackage{coolstr}
\begin{document}
\ifstrchareq{The Royal Court of Westminster}{0}{Court}{%
   TRUE
}{%
   FALSE
}
\end{document}
===== ><8 =====

I do not understand which value is needed in \ifstrchareq for the  
second argument.

Any hints?

TIA and kind regards, Friedrich
