3. What’s new for Solr in Sitecore 9

4. Highlight Search Results
• Highlighting in Solr allows fragments of documents that match the user’s
query to be included with the query response.
• No Configuration Changes
Parameters:
• hl – true/false
• hl.method
• hl.fl

5. Spell Checker
• This feature give users inline query suggestions based on other, similar
terms.
• Suggestions Source – Solr fields or external text file.
• Sorlconfig.xml changes are required to enable this feature.

6. Auto Suggest
• Solr has a "suggester" component called SuggestComponent. You use
this component to give users automatic suggestions for query terms.
• Solconfig.xml changes are required to enable this feature.

7. Group search Results
• Grouping in Solr can be used to group results together based on fields.
This is very similar to group-by clause in SQL with one important
difference.
• SQL group-by clauses (OR Solr facets) only return the counts per group
where as Solr Group option returns all the documents per group too.
• You do not have to configure anything in Solr to use this feature.
