------------------------------------
Summary: Consider using LuceneDictionary in suggester
Key: OAK-3594
URL: https://issues.apache.org/jira/browse/OAK-3594
Project: Jackrabbit Oak
Issue Type: Improvement
Components: lucene
Reporter: Tommaso Teofili
Assignee: Tommaso Teofili
Fix For: 1.4
Currently Lucene suggester is based on {{DocumentDictionary}} which builds
suggestions upon stored values of a certain field (in this case _:suggest_),
however it may be better to stick to plain indexed terms via a
{{LuceneDictionary}} as this would allow to save some space in the index
(:suggest field wouldn't have to be stored) and we can leverage per index
(configurable) analyzer in order to tweak how suggestions will be returned:
using a _KeywordAnalyzer_ would result in same behaviour we currently have,
using a tokenizing Analyzer will result in term level suggestions (tokens
instead of field values).
