> Support for using query engine for search suggestions
> -----------------------------------------------------
>
> Key: OAK-2176
> URL: https://issues.apache.org/jira/browse/OAK-2176
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: oak-lucene, oak-solr, query
> Affects Versions: 1.1.0
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Fix For: 1.1.6
>
>
> Related to OAK-2175 search engines are often used for term suggestions (e.g.
> for autocompletion, search as you type, etc.) which I think would be good to
> support also in Oak, especially having both Lucene
> (https://lucene.apache.org/core/4_10_0/suggest/org/apache/lucene/search/suggest/Lookup.html)
> and Solr (https://wiki.apache.org/solr/Suggester
> https://wiki.apache.org/solr/TermsComponent) already implementing this
> functionality.
