17 - pref: QueryAutoTruncate
21 no: only if * is added.
22 - "<br />(The * character would be used like so: <cite>Har*</cite> or <cite>*logging</cite>.)"

43 - to match words of the same base in a search (for example, a search for <cite>enabling</cite> would also match <cite>enable</cite> and <cite>enabled</cite>; REQUIRES ZEBRA).
45 - pref: QueryWeightFields
50 - ranking of search results by relevance (REQUIRES ZEBRA).
52 - pref: OpacGroupResults

66 - pref: TraceSubjectSubdivisions
71 - subdivisions for searches generated by clicking on subject tracings.
