------------------------------------------------------------
This issue still occurs with Solr 5.2.1, specifically during multi-shard
searches.
Please see updated test client in SolrGroupTest-5.2.1.tgz
Steps to test with Solr 5.2.1:
# tar xzf solr-5.2.1.tgz
# tar xzf SolrGroupTest-5.2.1.tgz
# ant -f SolrGroupTest/build.xml
The test portion of the ant script will generate:
{code}
test:
[exec] {
[exec] "responseHeader":{
[exec] "status":0,
[exec] "QTime":71,
[exec] "params":{
[exec] "q":"*:*",
[exec] "indent":"true",
[exec] "fq":"{!groupTest}",
[exec] "wt":"json",
[exec] "group.field":"manu_id_s",
[exec] "group":"true"}},
[exec] "grouped":{
[exec] "manu_id_s":{
[exec] "matches":0,
[exec] "groups":[]}}}
{code}
The fix can be deployed and tested by running:
# ./solr-5.2.1/bin/solr stop -all
# ant -f SolrGroupTest/build.xml fix_cloud_and_test
Expected results:
{code}
test:
[exec] {
[exec] "responseHeader":{

[exec] "QTime":156,

Updated test for Solr 5.2.1
> Post filter DelegatingCollector.finish not called for multi-shard queries

> Key: SOLR-7520
> URL: https://issues.apache.org/jira/browse/SOLR-7520
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 4.8
> Reporter: Eric Wheeler
> Attachments: SolrGroupTest-5.2.1.tgz, solrGroupTestEx.tgz
>
>
> The finish method for a DelegatingCollector post filter is not being called
> for queries specifying a fq filter, multiple shards, and grouping options.
> Recommend adding the following code to
> org.apache.solr.search.grouping.CommandHandler.searchWithTimeLimiter to call
> finish (if a DelegatingCollector is available) after calling search, but
> before obtaining totalHitCount:
> {code: title=org.apache.solr.search.grouping.CommandHandler line ~218}
> try {
> searcher.search(query, luceneFilter, collector);
> } catch (TimeLimitingCollector.TimeExceededException x) {
> partialResults = true;
> logger.warn( "Query: " + query + "; " + x.getMessage() );
> }
> /* Call finish of DelegatingCollector to complete post processing
> for multi-shard queries */
> if (filter.postFilter != null) {
> filter.postFilter.finish();
> }
> /* END: Call finish of DelegatingCollector to complete post processing
> for multi-shard queries */
> if (includeHitCount) {
> totalHitCount = hitCountCollector.getTotalHits();
> }
> {code}
