Trim start (and maybe end) of search queries

[curche]

Example cases
{{ kimi no na wa}}
{{ kimi no nowa}}
<< planetes>>
<>

The current regex pattern for the queries disallow space at the start.
Why? To avoid accidental triggers.

a <<valid>> query
a<<invalid>> query
another << invalid>> query
yet another <<invalid >> query

But that doesn't seem like a problem you say and for that case it would probably be fine but what if someone starts writing code that bit shifts left and right and we allow space at start

int value = 5;
int result = 1 << value & 0xFF >> 1; // valid trigger if we allow spaces before and/or after

Now the question becomes to allow or disallow this behavior.

Ideally code shud go inside ` or ``` and that could be handled separately hopefully?
if not, just let it get triggered
its a tradeoff I'm willing to have
its been a while I have seen someone ask about bitshift (except for a screenshot that contained a comparison between bitshifts between c/c++, lua, dart)
