I am using the latest version of DEVONagent Pro. The search set is “Web.”
Playing with this more, I have a semi-solution.
The search strings I am working with are “Concordat AND de AND Bologne” and “Concordat AND de AND Bologna”.
The “Concordat de Bologne” is the French title of the accord. It seems that the more common phrase in English is the “Concordat de Bologna,” following the Italian spelling of the name of the city, and mixing the French and Italian spellings. That said, there are many sites with the Bologne spelling.
By checking “Fuzzy” in the Language setting, agent shows results using the French or Italian spelling. With Fuzzy unchecked, results are shown only when searching with the Bologna spelling.
The weird part is that by searching for “Concordat AND de AND Bologna,” the top two sites have the Bologne spelling.
I don’t understand why the search using the French spelling shows no results when there are plenty of sites with that spelling, but at least I have a workaround.
