Hi,
I am using elasticsearch6.5 as single node, using 8GB of JVM and just 3% of memory is free. Will closing index using close API help to free heap memory .please tell what are the advantages of close index

Technically yes, but the warning in the [6.8 docs](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/indices-open-close.html#indices-open-close) also applies to 6.5: indices should only be closed on a temporary basis.
Also 6.5 is long past the [end of its supported life](https://www.elastic.co/support/eol), you should upgrade as a matter of urgency.
