Another
possibility would be to introduce marker tokens in your field, index
something like "$ member of technical staff $" and then, when
querying for exact matches, *add* the $ tokens to the beginning
and end of the query.
Just a note, I've hit problems with idf/tf when prefixing and
suffixing field boundaries in a single field like this. You will
probably have to override Similarity to ignore the prefix and suffix
tokens to avoid bad scores.
