Using Query Index Hints
You can use the hint keyword to allow GemFire’s query engine to prefer certain indexes.
In cases where one index is hinted in a query, the query engine filters off the hinted index (if possible) and then iterates and filters from the resulting values.
<HINT 'IDIndex'> SELECT * FROM /Portfolios p WHERE p.ID > 10 AND p.owner = 'XYZ'
If multiple indexes are added as hints, then the query engine will try to use as many indexes as possible while giving a preference for the hinted indexes.
<HINT 'IDIndex', 'OwnerIndex'> SELECT * FROM /Portfolios p WHERE p.ID > 10 AND p.owner = 'XYZ' AND p.value < 100
