Exclamation Amazon Metadata source plugin not working

Hi

I just installed Calibre, and I'd like to use it to download the right metadata and covers for my ebooks. Unfortunately, it seems that all "metadata source" plugins aren't working properly

Here some examples. I have a PDF ebook with:

Title: D Artiste
Author: Matte Painting


Of course the data is wrong. The title should be "Matte Painting", with multiple authors, in the D'artiste series.

When I try to download the metadata with various plugins, I have zero results. This is a log extract:


Amazon.com
Found 0 results
Downloading from Amazon.com took 1.11800003052
No matches found with query: u'http://www.amazon.com/s/?sort=relevancerank&field-author=Matte+Painting&field-title=D+Artiste&search-alias=stripbooks&unfiltered=1'

Barnes & Noble
Found 0 results
Downloading from Barnes & Noble took 1.51699995995
Querying: http://www.barnesandnoble.com/s?stor...Matte+Painting
No matches found with query: u'http://www.barnesandnoble.com/s?store=book&keyword=D+Artiste+Matte+Painting'


In the first case, the plugin send to Amazon this query:

field-author=Matte+Painting
field-title=D+Artiste


No surprise if it can't find anything. The plugin imho should be able to try also with a query like:

field-keywords=d+artiste+matte+painting

that would return the right result.

The second case with Barnes & Noble is weird. The query is right as it should be (try it in your browser):

http://www.barnesandnoble.com/s?store=book&keyword=D+Artiste+Matte+Painting


In my browser, this query gives the expected results (3 books, one of them is the book I was searching). But surprisingly, the plugin log states "Found 0 results".

Someone can explain this behavior?

Thanks

Yes and it would return lots of spurious results for other queries. Get your data right first, then try to download further metadata.

Not weird or surprising at all. The plugin log should state "Found 0 results" because not one of the returned authors is "Matte Painting" so there were no legitimate results found. Garbage in equals garbage out.

If you want to discuss the B&N results further you should do it in the [Metadata Source Plugin] Barnes & Noble thread.
