\documentclass{article}
\usepackage{xesearch}
\begin{document}
\tracingassigns=1
Hello World
\tracingassigns=0
\end{document}
The example shows that each word creates two command sequences,
example for "Hello":
{changing \Hello@cs@xs@words=undefined}
{into \Hello@cs@xs@words=\relax}
{changing \hello@ncs@xs@words=undefined}
{into \hello@ncs@xs@words=\relax}
I don't know the internals of xesearch.sty, but do you really need
the meaning \relax? Or it is just the usual side effect of TeX's
\csname?
In \xs@@F@Test you are using:
\expandafter\ifx\csname\xs@String @cs@xs@words\endcsname\relax
Perhaps you can replace it by \ifcsname ...\endcsname?
Yours sincerely
