Amit Jain updated OAK-2200:
---------------------------
Attachment: OAK-2200.patch
Added an {{entryCount}} parameter (defaults to 1000) for the lucene index
definition which indicates the max estimated entry count.
[~tmueller], [~chetanm] Please review the patch. Is there a need to add a
costFactor variable.
Chetan, the patch also contains a fix for an empty clause being added when a
node with a specific nodeType is indexed causing lucene to not return any
results.
> Tune cost calculation for lucene property index

> Though lucene provides an accurate count with {{IndexReader#numDocs}}, we may
> need to apply heuristics to constrain the value so that it is properly
> selected for indexed properties Vs other inappropriate indexes e.g wrt
> nodeType index.
