This sections defines settings concerning search suggestions.
Sets the number of suggestions returned and displayed in the layer attached to the search field.
Sets the Solr index field used to get suggestions from. A general advice is to use a field without stemming on it. For practical reasons this is currently the spell checker field.
If enabled, HTTPS will be used for querying suggestions. Otherwise HTTP will be used.
Since: version:1.4 / 1.7-dkd
When a user types multiple words into your search field they usually are split up into full keywords used in the query's q parameter and the last part being the partial keyword in the facet.prefix parameter. Enabling this setting moves everything into the facet.prefix parameter. This is usually only useful when using a string field as suggest / auto-complete source field.
Example - Here "Hello Solr" are the full keywords and the user started typing "World" so that "Wo" is used as the partial keyword:
"Hello Solr Wo" -> q=Hello Solr, facet.prefix=Wo (default)
"Hello Solr Wo" -> q=<empty>, facet.prefix=Hello Solr Wo (treatMultipleTermsAsSingleTerm)
