[BUG] Cardinality error when searching for certain string in blog

[lguariento]

From a blog page (https://exist-db.org/exist/apps/wiki/blogs/) searching for the string install (see here) in the upper-right box leads to a cardinality error:

PS: it must be interpreting 'install' as a special instruction/string, because even with one 'l' (instal) it goes through without errors.

[joewiz]

I think the difference is that there were hits for install but not for instal, so with the latter there was no hit processing, but in the former, there was a bug in the processing of the hits.

[lguariento]

Yes, you may be right. Why just install though? Setup is fine.

[lguariento]

Ah, I've found another one: no less than exist! https://exist-db.org/exist/apps/wiki/blogs/search.html?q=exist

[joewiz]

The error involves a templating function config:entry-url-from-entry, so whether there's an error or not probably depends on the hits themselves and whether they conform to what this function expects.
