Thomas Mueller reopened OAK-6735:
---------------------------------
I see "jcr:title" is hardcoded, that doesn't look right. What is the reason for
this? Could we at least make this configurable (e.g. using a system property)?
Also, it looks like properties with name ending with "_facet" have a special
meaning. What is a customer uses such property names... don't we have a good
escape mechanism (for example using the ":" prefix)?
> 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
> Assignee: Vikas Saurabh
> Priority: Major
> Fix For: 1.8, 1.7.11
>
> Attachments: IndexReadPattern.txt, LuceneIndexReadPattern.java,
> OAK-6735.patch
>
>
> 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).
