Autocomplete feature not working in Accelerator Storefront

We are exploring the autocomplete feature for Accelerator Storefront in hybris 4.8 but search box does not come up with suggestions/typeahead at all. The required entries are present in schema.xml and solrconfig.xml. Indexer operation was launched again. But autocomplete functionality is not working.

Please suggest how can we get autocomplete feature in storefront web site . We have taken following steps to do this in HMC. • Click Solr Item Types . • Mark the “Use for auto-complete” check box for particular indexes like name, category and brand and save this. • Update the indexes by launching indexer operation wizard.
