Hitesh Khamesra closed GEODE-2002.

> Key: GEODE-2002
> URL: https://issues.apache.org/jira/browse/GEODE-2002
> Project: Geode
> Issue Type: Bug
> Components: querying
> Reporter: Barry Oglesby
> Fix For: 1.1.0
>
>
> This is the same as GEM-1026.
> If an index is defined like:
> {noformat}
> <index name="instrumentTLAltIdIndex" from-clause="/instrument i,
> i.tradingLines tl" expression="tl.alternateReferences['SEDOL',
> 'INHOUSE_SEDOL']"/>
> {noformat}
> And a query is defined like:
> {noformat}
> <trace> select i from from /instrument i, i.tradingLines t where
> t.alternateReferences[$1]='BFNY8K9' with bind parameter 'SEDOL'.
> {noformat}
> Then, the {{instrumentTLAltIdIndex}} index won't be used when the query is
> executed.
> The message logged in the server log looks like (with {{indexesUsed(0)}}
> instead of {{indexesUsed(1)}}):
> {noformat}
> [info 2016/10/14 14:51:03.069 PDT <ServerConnection on port 57074 Thread 2>
> tid=0x3e] Query Executed in 3.645424 ms; rowCount = 14; indexesUsed(0)
> "<trace> select i from /instrument i, i.tradingLines t where
> t.alternateReferences[$1]='BFNY8K9'"
> {noformat}
> The {{CompiledIndexOperation generateCanonicalizedExpression}} method returns
> {{index_iter2.alternateReferences\[$1\]}} instead of
> {{index_iter2.alternateReferences\['INHOUSE_SEDOL'\]}}, and the
> {{AbstractMapIndex isMatchingWithIndexExpression}} method fails to match the
> index.
> The {{$1}} is generated by CompiledBindArgument
> generateCanonicalizedExpression.
> Also, note that the trace logging is incorrect on any query using a map index.
> The static query is defined like:
> {noformat}
> <trace> select i from from /instrument i, i.tradingLines t where
> t.alternateReferences['SEDOL']='BFNY8K9'
> {noformat}
> This logs a message in the server log like:
> {noformat}
> [info 2016/10/14 14:29:58.145 PDT <ServerConnection on port 56969 Thread 1>
> tid=0x3c] Query Executed in 54.36587 ms; rowCount = 16;
> indexesUsed(1):instrumentTLAltIdIndex-SEDOL(Results: 0) "<trace> select i
> from /instrument i, i.tradingLines t where
> t.alternateReferences['SEDOL']='BFNY8K9'"
> {noformat}
> The {{Results: 0}} part of the message is wrong. It should be {{Results: 16}}.
> The {{IndexTrackingQueryObserver beforeIndexLookup}} method saves the
> {{IndexInfo}} at {{key=instrumentTLAltIdIndex-SEDOL}}, but the
> {{afterIndexLookup}} method attempts to retrieve it using
> {{key=instrumentTLAltIdIndex}}. The {{IndexInfo}} is not found, so its
> results are not updated.
