[Koha] Authority Searching

[Norman Warrington]

I'm just setting up Koha 3.0 and have discovered that the Authorities 
search doesn't work properly for me. An Authorities search does work on 
the Liblime demo site but I have not been able to find any significant 
differences between my setup and the demo site setup. I am beginning to 
wonder if the problem relates to either Bug #3072:
http://bugs.koha.org/cgi-bin/bugzilla3/show_bug.cgi?id=3072

AND/OR the mailing list message:
http://lists.katipo.co.nz/pipermail/koha/2009-November/021107.html

Specifically, my problem is:
In Koha Admin, under the menu item "More" choose "Authorities". At the 
resulting screen a search using "Search Authorities" (subtext: "Enter 
authority heading ($a)) produces no results; however, a search using 
"Search Main Heading" produces the correct results.

Similarly, when importing a record, using the "Tag editor" at the end of 
the author field to open a screen and search for the authority record 
gives no results if the heading is in the "Main entry ($a only)" field 
but does work if the "Main entry" field is used.

Could someone tell me if my problem is related to Bug #3072 or if I'm 
missing something else?
Thanks,
Anne
