Can't search for some nicks

[coke]

https://logs.liz.nl/search.html?query=&type=starts-with&nicks=lizmat&channel=raku-dev&message-type=&entries-pp=50&from-yyyymmdd=2019-10-13&to-yyyymmdd=2021-11-16

generates many results for lizmat.

However, similar URLs for [Coke] and [Tux]

Yield no results for Coke, and results for "Tux" (no []'s) for Tux.

Escaping the []'s with \ has no impact on the search

[coke]

@lizmat points out that if I search for "Tux" or "Coke" and check the box "include nick aliases", I will get hits on those users.

This lets me do the search I want, but I argue that [Coke] with no aliases should also find me.

I'm failing to find messages when searching the #raku-beginner channel with tope in the nick field. If I check include nick aliases, I get an HTTP 500 error.

URLs showing what works / doesn't work...

WORK AS EXPECTED:

• Find matches for the word (not nick) tope This lists a bunch of matches. (Tangent / partial workaround. The list includes messages that do not contain the word tope but are written by the nick tope. But that's fair enough, and quite plausibly a good thing. It also provides something of a workaround; if nick searching ain't working, pop the nick in the basic query field instead.)

• The last message containing the word tope is written by guifa. So, find matches for the word tope and nick guifa This lists a bunch of matches, as expected.

• The last message in the first search above is written by tope and begins with the word "hehe". So, find matches for the word hehe This lists topes message, as expected. (Plus another bonus one, hehe.)

BUT:

• Find matches for the word hehe and nick tope No matches. This was not expected.

• Find matches for the word hehe and nick tope with include nick aliases checked I tried this after I found this issue. But I get:

This page isn’t working

logs.liz.nl is currently unable to handle this request.

HTTP ERROR 500

YET:

• Find matches for the word tope and nick guifa with include nick aliases checked This time I get the expected results. (Same as without include nick aliases checked.)

So there's something fundamentally broken about nick tope in a way that's not so for nick guifa.
