Ok, can I clarify something, if I put a phrase with quotes in it in the keywords field of a lens, I expect Kagi to search for it as a phrase, the same as if I typed it in the search box, not to search for literal quotes in the page text?
Is that what should be happening?
My guess is that you are improperly escaping the quotes in the keywords field and therefore searching for quote symbols on the page, or perhaps unescaped HTML or something like that. That would explain why some searches return odd looking results (because they happen to have quote symbols), and others like my example return nothing (because there happen to be no matching results that have quote symbols).
