Ignore accents and others diacriticals in search
For example, I have a "Wikipédia" entry but I want to search quickly by typing "wikipedia". At the moment, the entry is not returned but I think it could be a good think if it was the case.
More globally, I think that the search can be more powerful by searching in others fields like the note, the attributes and even URL and username. Maybe by "weighting" each field, to keep the most relevant entries at the top.
And we can imagine a fuzzy finding, I search "wkp" and the result "Wikipédia" is returned.
