In preparation for the next Yioop crawl, I am doing preliminary testing over at findcan.ca. One thing that I have now just added for the next crawl is support of [[https://en.wikipedia.org/wiki/Canonical_link_element|rel canonical]] links. This will hopefully improve the result quality by making it easier for Yioop to do deduplication. The changes are right now just in the git repository, but will appear in the download version as of version 1.02.
