-------------------------------
Attachment: (was: LuceneIndexReadPattern.java)
> Lucene Index: improved cost estimation by using document count per field
> ------------------------------------------------------------------------
>
> Key: OAK-6735
> URL: https://issues.apache.org/jira/browse/OAK-6735
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: lucene, query
> Affects Versions: 1.7.4
> Reporter: Thomas Mueller
> Fix For: 1.8
>
> Attachments: IndexReadPattern.txt, LuceneIndexReadPattern.java
>
>
> The cost estimation of the Lucene index is somewhat inaccurate because (by
> default) it just used the number of documents in the index (as of Oak 1.7.4
> by default, due to OAK-6333).
> Instead, it should use the number of documents for the given fields (the
> minimum, if there are multiple fields with restrictions).
> Plus divided by the number of restrictions (as we do now already).
