Document Oak - Lucene indexes do support sync + unique since
@@ -1726,25 +1726,6 @@ The Apache Lucene version currently used in Oak has a limit of about 2^31 docume
([this includes Lucene version 6](http://lucene.apache.org/core/6_5_0/core/org/apache/lucene/codecs/lucene62/package-summary.html#Limitations)).
If a larger index is needed, please use Apache Solr, which doesn't have this limit.
-### <a name="lucene-vs-property"></a>Lucene Index vs Property Index
-
-Lucene based index can be restricted to index only specific properties and in that
-case it is similar to [Property Index](query.html#property-index). However it differs
-from property index in following aspects
-
-1. Lucene index is Asynchronous - Lucene indexing is done asynchronously with a default
- interval of 5 secs. If there are lots of writes and those writes are related to what
- is being indexed then it might cause further delay. Compared to this the property index
- are always synchronous and upto date.
-
- So if in your usecase you need the latest result then prefer _Property Indexes_ over
- _Lucene Index_. Oak 1.6 supports [Near Realtime Indexing](indexing.html#nrt-indexing)
- which reduce the lag considerably. With this you should be able to use lucene indexing
- for most cases
-
-2. Lucene index cannot enforce uniqueness constraint - By virtue of it being asynchronous
- it cannot enforce uniqueness constraint.
