Plugin config page no longer works: Undefined "cat" field error

[ksclarke]

I did a pull to the latest 'develop' version (and am using Omeka 1.5.1). I deleted my Solr data directory and did an uninstall and reinstall of the SolrSearch plugin. When I do the reinstall I try to configure the plugin on the settings/configure page (using localhost, port 8983, /solr/, 20, Occurrences, and 25 (as configuration values)). When I try to save the settings, I do not get anything in the errors.log but I get a displayed error: "Invalid Solr server host, port, or core."

When I look at the Solr logs I see an undefined "cat" field error:

Clicking on index doesn't work either. On another machine where I just installed the latest git changes but didn't wipe the index or uninstall/reinstall the index is still there and can be queried. Changes to the configure/settings page, though, also gives the same error message.

I look in the solrconfig.xml file and I see the ping query is: qt=dismax&q=solr&start=3&fq=id:[* TO ]&fq=cat:[ TO *]

So, I removed the &fq=cat:[* TO *] part of the ping query and then everything worked fine. So I'm guessing the ping just started to be used to give a better error page. Users I think though would need to delete that part of the ping query or make sure that the field is created in Solr so they don't get this error.

Looks like this is a remnant from the older default solrconfig.xml that shipped in Solr 1.4.x. Need to take a look at the new defaults and yank out the stuff that is for the example app.

Maybe make a note of it, too, in documentation since I'm not using the example solr app but a barebones one I had around from another project (so it's out there in the wild and folks may do what I did and stumble on the problem).
