-== Multi-term Did You Mean search suggestions ==
-
-Expanding on the previous single-class, single-term search suggestion
-development, this feature provides suggestions for single-class searches
-with multiple terms.
-
- * The Library Settings that were previously used to control the global
-behavior of search suggestions have been moved to search class
-configuration fields. This was done because the data in each search
-class benefits from different setting values. If the Library Settings
-had been set, they will be used to update the corresponding search
-class configuration fields. Regardless, Evergreen administrators are
-recommended to review the settings.
-
- * If a patron's search matches a variant or non-preferred heading from
-an authority record, if the main heading of that authority is linked
-to at least bibliographic record, the system will provide that main
-heading as a suggestion as well, along with spelling-corrected suggestions.
-
- * Quoted phrases in user input require strict term order and adjacency
-for the phrase portion of the suggestion generated for the phrase(s),
-whereas unquoted input (or the portion that is not quoted) does not.
-
-=== MARC Search/Facet Class field additions ===
-
- * variant_authority_suggestion Whether this class should attempt variant authority suggestions based on search-class/browse-axis mapping
- * symspell_transfer_case Whether suggestions should retain user-supplied letter case
- * symspell_skip_correct Only supply suggestions to misspelled words
- * symspell_suggestion_verbosity Setting that controls the amount of effort, and therefore time, spent on suggestion generation
- * max_phrase_edit_distance Maximum average per-word edit distance when evaluating suggestions
- * suggestion_word_option_count Maximum alternate suggestions per word
- * max_suggestions Maximum suggstions to present
- * low_result_threshold Maximum hit count beyond which suggestions are not provided
- * min_suggestion_use_threshold Minimum number of times a suggestion must exist in the corpus
- * pg_trgm_weight Weight of the trigram similarity metric; 0 avoids calculation costs
- * soundex_weight Weight of the soundex similarity metric; 0 avoids calculation costs
- * keyboard_distance_weight Weight of the keyboard distance similarity metric; 0 avoids calculation costs
-
-=== Upgrade ===
-
-If the databse has authority records that are linked to bilbiographic
-records, a reingest of the search suggestion dictionary is recommended.
-
-Instructions for performing that reingest are included in the database
-update scripts and will be output to the log when those scripts are
-run.
