Some events as background.
I have made some changes to schema.xml to define a new field type and have a
few string fields use this field type.

I reloaded the core.
Upon suggestion from this group, rather than just re-indexing (because it might
not refresh all segments appropriately), I deleted the "data" directory for the
core and then re-indexed.
The new data directory contained an "index" directory with a single file called
write.lock and nothing else. There was no tlog directory (which seems notable
because we used to have one).
But things were behaving OK - that is searches worked and returned documents --
so I didn't think much of it.
This was Wednesday.
Today, we received errors that the core didn't exist. When I connected to the
admin interface, I had the error "Error creating core. No system property or
default value specified for jdbcdir".
Now, our solconfig.xml does refer to "${jdbcdir}" and core.properties defines
this setting as a path and that path exists. These config files all exist and
haven't been touched in several months. The permissions have not been changed.
I replaced "${jdbcdir}" with its value from core.properties. Received the same
error about two other settings which I also replaced with hard-coded values
which are defined in core.properties and I am now able to load the core.
My question is - what on earth just happened?
Once the core was reloaded, I re-indexed our data which completed in seconds
(usually about 45 minutes) and searches returned no matches (0 documents).
Then, I replaced the basically empty data directory with a backup I made of the
contents as of Wednesday and re-indexed and searches are working again (they
return documents). After doing this, I tried to put back the original
solrconfig.xml but it still errored out with the same errors about missing
default or system properties.

Any idea what happened and how I can go back to using my original
solrconfig.xml which does not have hard-coded paths and parameters??
Also any thoughts on what went wrong with the re-index and why it never created
any segment files in the index directory?
Are these two things related?
Many thanks,
Teresa
