+Stream through operations in bundles and evaluate expressions.
+Supports parallel processing for better performance.
 
-The JMESPath expression is evaluated against each operation's JSON structure.
-Only operations where the expression returns a non-null value are output.
-
-Output formats:
-  jsonl - Output matching operations as JSONL (default)
-  count - Only output count of matches`,
-
-		Example: `  # Extract DID field from all operations
-  plcbundle query 'did' --bundles 1-10
+Simple Mode (--simple):
+  Fast field extraction using dot notation (no JMESPath parsing):

+  Performance: should be faster than JMESPath mode
+  Limitations: No filters, functions, or projections
