I have a JSON field that is an array of elements composed of oid, instance and value. Most of my queries will be on a combination of oid and instance.

What is the syntax for creating such an index if the combination of oid and instance is unique?

[
 { 'oid' : '1.3.1', 'instance' : '0', 'value' : '0' }, 
 { 'oid' : '1.3.1', 'instance' : '2', 'value' : '9' },
 { 'oid' : '1.3.6.1', 'instance' : '0', 'value' : '1' },
 { 'oid' : '1.3.6.9', 'instance' : '0', 'value' : '1' }
]

Thanks, Avi

Create full-text index and search for substring. Another option would be to use intermediate indexed table that keeps parsed values and points to the one with JSON.
