That definitely sounds like the proper way to go + will try. Im not
too concerned w/ my keys coming back just that I can't seem to run the
DataImportHandler w/o one.
I was able to temporarily get around it by returning it in the entity
query. Ie:
<entity query="select concat(col1,col2,col3,col4) as id">
<field name="id" column="id" />
</entity>
BTW, the DataImportHandler seems to still be a "patch", is there an
estimation of if/when it will appear in trunk?
Thanks!

Something that *seems* possible but I've never actaully tried is
writting
a "ConcatTokenFilterFactory" that queues up all the tokens and joins
them together (using some confiured string, defaulting to "") then
you
could in theory do something like this...
<fieldType name="compositeKeyType" class="solr.TextField"
omitNorms="true">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.ConcatTokenFilterFactory" delim="-"/>
<analyzer>
</fieldType>
...
<field name="compositeKey" type="compositeKeyType" />
<uniqueKey>compositeKey</uniqueKey>
...
<copyField source="type" dest="compositeKey"/>
<copyField source="numId" dest="compositeKey"/>
...
that *might* work ... but things would be a little weird when
viewing your
results (compositeKey would have to be multivalued, and it would
return as
an array)
