1 == Multi-term Did You Mean search suggestions ==
3 Expanding on the previous single-class, single-term search suggestion
4 development, this feature provides suggestions for single-class searches
7 * The Library Settings that were previously used to control the global
8 behavior of search suggestions have been moved to search class
9 configuration fields. This was done because the data in each search
10 class benefits from different setting values.
12 * If a patron's search brings back a suggestion that matches an authority
13 variant heading, the system will provide the main heading as a suggestion
14 as well, along with spelling-corrected suggestions.
16 * Quoted phrases in user input require strict term order and adjacency
17 for the phrase portion of the suggestion generated for the phrase(s),
18 whereas unquoted input (or the portion that is not quoted) does not.
