> URL: https://issues.apache.org/jira/browse/NIFI-3248
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0, 0.5.0, 0.6.0, 0.5.1, 0.7.0, 0.6.1, 1.1.0, 0.7.1,

>
> GetSolr holds the last query timestamp so that it only fetches documents
> those have been added since the last query.
> However, since the timestamp filter is not properly formatted as a valid time
> range filter, GetSolr never fetches newly added documents.
> The code has been the same in the [0.5
> branch|https://github.com/apache/nifi/blob/support/nifi-0.5.x/nifi-nar-bundles/nifi-solr-bundle/nifi-solr-processors/src/main/java/org/apache/nifi/processors/solr/GetSolr.java#L202],
> so it seems it hasn't been working as expected.
> {code}
> // if initialized then apply a filter to restrict results from the
> last end time til now
> if (initialized) {
> StringBuilder filterQuery = new StringBuilder();
> filterQuery.append(context.getProperty(DATE_FIELD).getValue())
> // This should be a square bracket :[
> .append(":{").append(lastEndDatedRef.get()).append(" TO ")
> .append(currDate).append("]");
> solrQuery.addFilterQuery(filterQuery.toString());
> logger.info("Applying filter query {}", new
> Object[]{filterQuery.toString()});
> }
> {code}
