When going to the linking screen in muc there is a search button, what is actually happening when it is searching? It appears to be looking for matches.
I am not sure I understand your question.
At that point it is searching our online database, to show possible matches for your local album entry.
What concerns me is that where there are multiple matches it is often choosing the wrong result.
You do the choosing, not the program.
Does this have any effect on the connect viewable page or the data in my muc collection?
Yes, the linking is necessary for Connect, here's the full story:http://www.collectorz.com/music/manual/linking.html
Linking does not affect your local collection data, other than the filling of the ClzAlbumID field.
I seem to have a lot of albums that are not linked, can't tell how many as the screen does not tell me the total?
You can find out by finding all albums with ClzAlbumID = 0.
With 5000 albums there appears to be a lot not linked, despite me submitting everything in my collection to your database (except for albums already there)
If you submitted AFTER adding it to your database, your local entry does not have the ID of the online entry yet.
Do I still link these albums with wrong results?, surely I don't have to change all this manually?
No, definitely do NOT link to wrong results!
But yes, you will have to link manually. But only once.
Also what about albums that have no barcode entered? I presume you match by disc id for connect? what about digital albums?
The link screen uses the CD-ID and Artist/Title for matches, it works just like the Add Automatically screen (in fact, it IS the Add Auto screen in a different mode).
Why does the search routine match albums to discogs, usually incorrectly, what does this have to do with getting my albums on connect ? I thought that I read in the manual that linking was a matter of finding the album in the central database and making a link so that tracks and covers were used from there instead from my collection. Therfore I would have thought unless there was a definite link the album would be uploaded unlinked with just my basic information? Is this correct?
Yes, that is correct. Make sure you read this:http://www.collectorz.com/music/manual/linking.html
if so why would it match an artist like "King King" with a wild guess like "B.B. King" does that mean it will show that album on connect with tracks and covers from BB King for eaxample?
If the link screen cannot find a match by CD-ID, then it will search by artist/title, which will of course produce more "fuzzy" search results. Nothing new, nothing strange, exactly the same as in the Add Auto screen. The search results are just that: search results. It is *you* who does the matching.
But yes, if you match King King to BB King, then yes, your Connect account will show a BB King track list for that album... (not a good idea).
Once I've uploaded and if the info is incorrect can I delete the entire albums in connect.......this feels very shaky....hope I'm wrong as the idea is good.
Nothing shaky, nothing new. This has been around and working like this since October 2010
