I'm using Sitecore 9 update 1 with SXA 1.7, I configured the auto suggester in the Solr, the suggest.count is 30 and the maximum predictive results count for the SXA search box is 30 also, but the returning results is always 5 although there is more data indexed in the Solr, I tried many things like changing numbers or removing it but still the same.

Here is my configuration for the auto suggester :

<searchComponent name="suggest" class="solr.SuggestComponent">
 <lst name="suggester">
 <str name="name">sxaSuggester</str>
 <str name="lookupImpl">BlendedInfixLookupFactory</str>
 <str name="dictionaryImpl">DocumentDictionaryFactory</str>
 <str name="contextField">_language</str>
 <str name="field">suggestion_s</str>
 <str name="suggestAnalyzerFieldType">text_suggester</str>
 <str name="payloadField">templatedisplayname_s</str>
 <str name="buildOnStartup">true</str>
 <str name="buildOnCommit">false</str>
 </lst>
 </searchComponent>
 <requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy" >
 <lst name="defaults">
 <str name="suggest.dictionary">sxaSuggester</str>
 <str name="suggest">true</str>
 <str name="suggest.onlyMorePopular">true</str>
 <str name="suggest.count">30</str>
 <str name="suggest.collate">true</str>
 </lst>
 <arr name="components">
 <str>suggest</str>
 </arr>
 </requestHandler>

Unfortunately, it's hardcoded to have 5 suggestions. It definitely shouldn't be done that way and I will register a task in our backlog to change it and make it configurable.

As a workaround, you could override SolrSuggester or implement your own suggester by creating a class which implements ISuggester interface. At the end just replace SXA implementation by your one in the DI container.

You can pass a number of suggestions like that:

SuggestHandlerQueryOptions options = new SuggestHandlerQueryOptions

 Parameters = new SuggestParameters
 
 Count = NUMBER_OF_SUGGESTIONS
 

Investigate Sitecore.XA.Foundation.VersionSpecific.Services.SolrSuggester to have a full picture how the implementation should look like.
