> Wrong output for the range query with wildcard character
> --------------------------------------------------------
>
> Key: GEODE-9632
> URL: https://issues.apache.org/jira/browse/GEODE-9632
> Project: Geode
> Issue Type: Bug
> Components: querying
> Affects Versions: 1.13.1, 1.14.0
> Reporter: Mario Kevo
> Assignee: Mario Kevo
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> We are using a range index on an attribute that is defined as HashMap.
> The problem is when we are using wildcard character(%), there is no results
> for the query despite of there are some entries that meet the condition we
> are checking.
> There is an example:
>
> {code:java}
> gfsh>query --query="<trace>SELECT e.key, e.value from
> /example-region.entrySet e where e.value.positions['SUN'] LIKE
> '342234525745'"
> Result : true
> Limit : 100
> Rows : 1
> Query Trace : Query Executed in 9.082156 ms; indexesUsed(1):index1(Results: 1)
> gfsh>query --query="<trace>SELECT e.key, e.value from
> /example-region.entrySet e where e.value.positions['SUN'] LIKE
> '34223452574%'"
> Result : true
> Limit : 100
> Rows : 0
> Query Trace : Query Executed in 4.677162 ms; indexesUsed(1):index1(Results:
> 100)
> {code}
> As we are using indexes to have a better performance of executing a query it
> first need to check how many entries has that field which we are looking for.
> It stores it in index results and then check how many of them meet condition
> we defined in our query.
> The problem is that there is parameter INDEX_THRESHOLD_SIZE which default
> value is 100. If there is a lot of entries in the region it will write just
> first 100 entries that is found.
> This parameter can be changed while starting servers by adding
> *-Dgemfire.Query.INDEX_THRESHOLD_SIZE=<value>*, but if we set it to a higher
> value than the limit in the query is, it will overwrite it. So there should
> be some changes to take this attribute into account.
