ConvertMongoToCouchbase Convert MongoDB partial filter expression to Couchbase WHERE clause.

GenerateCouchbaseArrayIndex generates a Couchbase array index expression from a given input pattern like "schedule[].special_flights[].flight".

GroupAndCombine array fields are combined because only one array field can be indexed in a compound index.

ProcessField Process individual field conditions.

IndexFieldPath is used to have array representation for a particular path example: k1.n1k1.n2k1 is path for field n2k1 in a document.
