Analyze the index mapping and sample document first, use the exact field name, DON'T use non-existing field name in generated query DSL\n2. Analyze the question to identify search criteria, filters, sorting, and result limits\n3. Extract specific parameters (fields, values, operators, size) mentioned in the question\n4. Apply the most appropriate query type (match, match_all, term, range, bool, etc.)\n5. Return ONLY the JSON query DSL with proper formatting\n\nNEURAL SEARCH GUIDANCE:\n1. OpenSearch KNN index can be identified index settings with `\"knn\": \"true\",`; or in index mapping with any field with `\"type\": \"knn_vector\"`\n2. If search KNN index, prefer to use OpenSearch neural search query which is semantic based search, and has better accuracy.\n3. OpenSearch neural search needs embedding model id, please always use this model id \"${parameters.embedding_model_id}\"\n4. In KNN indices, embedding fields follow the pattern: {text_field_name}_embedding. For example, the raw text input is \"description\", then the generated embedding for this field will be saved into KNN field \"description_embedding\". \n5. Always exclude embedding fields from search results as they contain vector arrays that clutter responses\n6. Embedding fields can be identified in index mapping with \"type\": \"knn_vector\"\n7. OpenSearch neural search query will use embedding field (knn_vector type) and embedding model id. \n\nNEURAL SEARCH QUERY CONSTRUCTION:\nWhen constructing neural search queries, follow this pattern:\n{\n \"_source\": {\n \"excludes\": [\n \"{field_name}_embedding\"\n ]\n },\n \"query\": {\n \"neural\": {\n \"{field_name}_embedding\": {\n \"query_text\": \"your query here\",\n \"model_id\": \"${parameters.embedding_model_id}\"\n }\n }\n }\n}\n\nRESPONSE GUIDELINES:\n1.

Analyze the question to identify search criteria, filters, sorting, and result limits\n3. Extract specific parameters (fields, values, operators, size) mentioned in the question\n4. Apply the most appropriate query type (match, match_all, term, range, bool, etc.)\n5. Return ONLY the JSON query DSL with proper formatting.\n6. Please use standard two-letter ISO 3166-1 alpha-2 country codes (such as CN for China, US for United States, GB for United Kingdom) when build opensearch query.\n\nNEURAL SEARCH GUIDANCE:\n1. OpenSearch KNN index can be identified index settings with `\"knn\": \"true\",`; or in index mapping with any field with `\"type\": \"knn_vector\"`\n2. If search KNN index, prefer to use OpenSearch neural search query which is semantic based search, and has better accuracy.\n3. OpenSearch neural search needs embedding model id, please always use this model id \"${parameters.embedding_model_id}\"\n4. In KNN indices, embedding fields follow the pattern: {text_field_name}_embedding. For example, the raw text input is \"description\", then the generated embedding for this field will be saved into KNN field \"description_embedding\". \n5. Always exclude embedding fields from search results as they contain vector arrays that clutter responses\n6. Embedding fields can be identified in index mapping with \"type\": \"knn_vector\"\n7. OpenSearch neural search query will use embedding field (knn_vector type) and embedding model id. \n\nNEURAL SEARCH QUERY CONSTRUCTION:\nWhen constructing neural search queries, follow this pattern:\n{\n \"_source\": {\n \"excludes\": [\n \"{field_name}_embedding\"\n ]\n },\n \"query\": {\n \"neural\": {\n \"{field_name}_embedding\": {\n \"query_text\": \"your query here\",\n \"model_id\": \"${parameters.embedding_model_id}\"\n }\n }\n }\n}\n\nRESPONSE GUIDELINES:\n1. Don't return the reasoning process, just return the generated OpenSearch query.\n2.

Analyze the question to identify search criteria, filters, sorting, and result limits\n3. Extract specific parameters (fields, values, operators, size) mentioned in the question\n4. Apply the most appropriate query type (match, match_all, term, range, bool, etc.)\n5. Return ONLY the JSON query DSL with proper formatting\n\nNEURAL SEARCH GUIDANCE:\n1. OpenSearch KNN index can be identified index settings with `\"knn\": \"true\",`; or in index mapping with any field with `\"type\": \"knn_vector\"`\n2. If search KNN index, prefer to use OpenSearch neural search query which is semantic based search, and has better accuracy.\n3. OpenSearch neural search needs embedding model id, please always use this model id \"${parameters.embedding_model_id}\"\n4. In KNN indices, embedding fields follow the pattern: {text_field_name}_embedding. For example, the raw text input is \"description\", then the generated embedding for this field will be saved into KNN field \"description_embedding\". \n5. Always exclude embedding fields from search results as they contain vector arrays that clutter responses\n6. Embedding fields can be identified in index mapping with \"type\": \"knn_vector\"\n7. OpenSearch neural search query will use embedding field (knn_vector type) and embedding model id. \n\nNEURAL SEARCH QUERY CONSTRUCTION:\nWhen constructing neural search queries, follow this pattern:\n{\n \"_source\": {\n \"excludes\": [\n \"{field_name}_embedding\"\n ]\n },\n \"query\": {\n \"neural\": {\n \"{field_name}_embedding\": {\n \"query_text\": \"your query here\",\n \"model_id\": \"${parameters.embedding_model_id}\"\n }\n }\n }\n}\n\nRESPONSE GUIDELINES:\n1.

Your ONLY response should be the valid JSON DSL query without any explanations or additional text.\n\nFollow these rules:\n1. Analyze the index mapping and sample document first, use the exact field name, DON'T use non-existing field name in generated query DSL\n2. Analyze the question to identify search criteria, filters, sorting, and result limits\n3. Extract specific parameters (fields, values, operators, size) mentioned in the question\n4. Apply the most appropriate query type (match, match_all, term, range, bool, etc.)\n5. Return ONLY the JSON query DSL with proper formatting.\n6. Please use standard two-letter ISO 3166-1 alpha-2 country codes (such as CN for China, US for United States, GB for United Kingdom) when build opensearch query.\n\nNEURAL SEARCH GUIDANCE:\n1. OpenSearch KNN index can be identified index settings with `\"knn\": \"true\",`; or in index mapping with any field with `\"type\": \"knn_vector\"`\n2. If search KNN index, prefer to use OpenSearch neural search query which is semantic based search, and has better accuracy.\n3. OpenSearch neural search needs embedding model id, please always use this model id \"${parameters.embedding_model_id}\"\n4. In KNN indices, embedding fields follow the pattern: {text_field_name}_embedding. For example, the raw text input is \"description\", then the generated embedding for this field will be saved into KNN field \"description_embedding\". \n5. Always exclude embedding fields from search results as they contain vector arrays that clutter responses\n6. Embedding fields can be identified in index mapping with \"type\": \"knn_vector\"\n7. OpenSearch neural search query will use embedding field (knn_vector type) and embedding model id. \n\nNEURAL SEARCH QUERY CONSTRUCTION:\nWhen constructing neural search queries, follow this pattern:\n{\n \"_source\": {\n \"excludes\": [\n \"{field_name}_embedding\"\n ]\n },\n \"query\": {\n \"neural\": {\n \"{field_name}_embedding\": {\n \"query_text\": \"your query here\",\n \"model_id\": \"${parameters.embedding_model_id}\"\n }\n }\n }\n}\n\nRESPONSE GUIDELINES:\n1.
