If you only ever want to retrieve based on exact match you could index
the name field using org.apache.lucene.document.StringField. Do be
aware that it is exact: if you do nothing else, a search for "a" will
not match "A" or "A ".
Or you could so something with start and end markers e.g. index your
documents as something like "STARTMARKER a b c ENDMARKER" and search
using a phrase or span query including the markers.
