ES index counts

Observation

• we are starting re-indexing from the JSF Admin Center Screen
• we are getting the number of documents from this same screen
  Looking at the underlying code here:
  https://github.com/nuxeo/nuxeo/blob/master/nuxeo-features/nuxeo-elasticsearch/nuxeo-elasticsearch-web/src/main/java/org/nuxeo/elasticsearch/web/admin/ElasticSearchManager.java#L197
  It is not sure this is the best approach

Expectation

We should be able to extract the number of documents from the indices themselves without having to do a query.
Below on the screen, we have indices metadata that seem to provide a # of documents, but:

• the number is different on each chard
• the number if about 10x bigger than the one we compute using a query

Suggestion

• review the way we do the count
• check that this is consistent when we do re-index several times

Remarque

At this point, we are not excluding the option that there are problems tied to the re-indexing itself. The goal is to make sure that the counters are 100% reliable.
