8 - the Zebra search engine. It is recommended to use Zebra; the option to not use Zebra is deprecated and is not guaranteed to work.
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).
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
57 - PazPar2 to group similar results on the OPAC. This requires that PazPar2 is set up and running.
59 - pref: TraceCompleteSubfields
64 - subject tracings in the OPAC and Staff Client to search only for complete-subfield matches.
66 - pref: TraceSubjectSubdivisions
71 - subdivisions for searches generated by clicking on subject tracings.
78 - 'ICU Zebra indexing. Please note: This setting will not affect Zebra indexing, it should only be used to tell Koha that you have activated ICU indexing if you have actually done so, since there is no way for Koha to figure this out on its own.'
81 - Show tabs in OPAC and staff-side advanced search for limiting searches on the
82 - pref: AdvancedSearchTypes
84 - "fields (separate values with |). Tabs appear in the order listed.<br/>"
85 - "<em>Currently supported values</em>: Item types (<strong>itemtypes</strong>), Collection Codes (<strong>ccode</strong>) and Shelving Location (<strong>loc</strong>)."
88 - pref: expandedSearchOption
93 - '"More options" on the OPAC and staff advanced search pages.'
96 - By default, sort search results in the staff client by
97 - pref: defaultSortField
101 popularity: total number of checkouts
102 callnumber: call number
103 pubdate: date of publication
108 - pref: defaultSortOrder
115 - pref: displayFacetCount
121 - facet counts. The relevance of these numbers highly depends on the value of the maxRecordsForFacets preference. Applies to OPAC and staff interface.
124 - pref: numSearchResults
126 - results per page in the staff client.
128 - By default, sort search results in the OPAC by
129 - pref: OPACdefaultSortField
133 popularity: total number of checkouts
134 callnumber: call number
135 pubdate: date of publication
140 - pref: OPACdefaultSortOrder
149 - pref: maxItemsInSearchResults
151 - items per biblio in the search results
153 - Build facets based on
154 - pref: maxRecordsForFacets
157 - records from the search results.
160 - pref: OPACnumSearchResults
162 - results per page in the OPAC.
164 - pref: OPACItemsResultsDisplay
169 - "an item's library, location and call number in OPAC search results."
171 - Truncate facets length to
172 - pref: FacetLabelTruncationLength
174 - characters, in OPAC/staff interface.
