Before writing a CREATE CORTEX SEARCH SERVICE statement:

1. Read references/parameters.md to review all available parameters and their defaults.
2. For each parameter, decide whether the user's request implies a non-default value.
3. Include only the parameters that differ from the default or that the user explicitly requested.
4. Never use CREATE OR REPLACE — always use CREATE CORTEX SEARCH SERVICE IF NOT EXISTS where supported.
5. Choose between single-index syntax (ON <search_column>) and multi-index syntax (TEXT INDEXES ... VECTOR INDEXES ...) based on the user's retrieval requirements; use multi-index when both keyword and vector similarity search are needed.
6. Always specify WAREHOUSE and TARGET_LAG; they are required.
7. Supply a PRIMARY KEY whenever the source table has a natural unique key — it enables optimized incremental refresh.
8. Default REFRESH_MODE is INCREMENTAL; only override to FULL when the source table lacks change-tracking support.
