8 - the Zebra search engine. Searches are very slow on even modest sized collections when Zebra is off.
10 - When Zebra is not in use, translate the following MARC fields to the following indexes (each line should look something like <code>'indexname' => '100a,245a,500*',</code>):
11 - pref: NoZebraIndexes
16 - Perform wildcard searching (where, for example, <cite>Har</cite> would match <cite>Harry</cite> and <cite>harp</cite>)
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>.)"
29 - to match similarly spelled words in a search (for example, a search for <cite>flang</cite> would also match <cite>flange</cite> and <cite>fang</cite>; REQUIRES ZEBRA).
31 - pref: QueryRemoveStopwords
36 - stopwords specified in Koha when searching. (Only applies when Zebra is off).

45 - pref: QueryWeightFields
50 - ranking of search results by relevance (REQUIRES ZEBRA).
