Implement Suggestions & Spell check in full-text search Using Query builder in AEM

Question

While implementing full-text search Using Query builder in AEM-6.4, I need to add feature for spell check and suggestion.

Is there any way to implement this using predicate map properties in Query builder, Indexing etc

Updated:

Code snippet -

@Inject
private Suggester suggester;

final String[] suggetions = suggester.getSuggestions(session, "searchGlobal", queryString, true);
final String spellCheck = suggester.spellCheck(session, queryString);

suggetions - is returning empty value & suggester.spellCheck(session, queryString) - is throwing Nullpointer Exception

AEM internally uses Jackrabbit Oak JCR implementation, which uses lucene indexing for repository.

If we look at Jackrabbit Oak Lucene Index documentation. We would need to do 2 steps

Create required index
Use query, for example below to use the suggestion index created above

SELECT rep:suggest() FROM [nt:base] WHERE SUGGEST('test') AND ISDESCENDANTNODE('/a/b')

Similar way spell check can be also implemented, would just need property configured in index accordingly.

I don't wan to write query in SQL format, I need to create query using predicate maps. How will step 2 be implemented? – Abhishek Sinha Jan 07 '20 at 05:03
