--------------------------------------------------

             Summary: Invalid queryStrings cause lucene searches to hang in in PR with multiple nodes
                 Key: GEODE-2943
                 URL: https://issues.apache.org/jira/browse/GEODE-2943
             Project: Geode
          Issue Type: Bug
          Components: lucene
            Reporter: Shelley Lynn Hughes-Godfrey


Some invalid query strings might be "`*`" or " ".

When used with a single node dataStore, we see the correct Exception returned:
```
gfsh>search lucene --name=testIndex --region=/testRegion --queryStrings="*" --defaultField=__REGION_VALUE_FIELD
Could not process command due to GemFire error. An error occurred while searching lucene index across the Geode cluster: Leading wildcard is not allowed: __REGION_VALUE_FIELD:*
```
However, with multiple nodes, the query hangs. 

Jason debugged this a bit and found:
```
the remote nodes fail in the function with this stack trace (where we will probably need to try/catch any lucene exception)
