I can’t reproduce this issue; this search should not cause this error message. The code on line 811 (assuming you’re on the latest version) should not run at all with this search query.
Can you perhaps provide a full stacktrace of the error? I’d need to see where this error originated, what called the relevanssi_stripos() function and with what parameters.
With just this information, there’s nothing I can do about this.
Thanks.
Here a the full stacktrace:

Ah, I see, this happens in excerpt-building. Is this a legit search in the first place, is this something that is meaningful to search on your site or is it just spam? If it’s spam, I would recommend just blocking it.
Anyway, I’ll fix this in the next version. If you want a quick fix, replace this in lib/utils.php
$needle_regex = str_replace(
array( '?', '*' ),
array( '.', '.*' ),
$needle
);
with this:
$needle_regex = str_replace(
array( '?', '*' ),
array( '.', '.*' ),
preg_quote( $needle, '/' )
);
I think it is spam, but it’s always better when the code doesn’t generate warnings or errors 🙂
Thanks for the fix!
When you talk about blocking, what do you mean? Relevanssi can perform this?
Great plugin and support 😉
Agree about the warnings.
I was thinking of keyword blocking (like this).
(I’ve been thinking about integrating something like that within Relevanssi, either built-in or as an add-on plugin, an easy way to do keyword blocking, blocking searches with Chinese characters or cyrillic text and so on. That might be helpful.)

It’s a good idea! It will be useful!
