The general practice is to use the same analyzer for indexing and searching.

You can search the lucene and solr mailing lists for denormalize

This isn't ideal, but if you have a defined list of such terms, you
may find it easier to filter these terms out into a separate field
for indexing.

If I understand the problem correctly, it is: given a [job
