Which is NOT a valid search type available in SAP HANA views?

In SAP HANA views, the valid search types are designed to provide flexible and powerful search capabilities, particularly for handling complex data and various search scenarios. Among the given options, Boolean search is not recognized as a valid search type available in SAP HANA views.

Fuzzy search is a type of search that allows for approximate matching of search terms, helping users find results even when there are minor discrepancies or misspellings. Freestyle search refers to a more free-form and natural language search experience, enabling users to input queries in a more conversational manner. Point-based ranking, although not a standard terminology in typical search types, relates to specific ranking mechanisms used to evaluate and order search results based on relevance or significance.

In this context, Boolean search traditionally uses logical operators (AND, OR, NOT) to create specific search criteria. While it is a well-known concept in search algorithms, it is not explicitly designated as a search type in SAP HANA views, which rely more on the functionalities provided by fuzzy and freestyle searches. Therefore, identifying Boolean search as the option that does not fit within the valid search types available in SAP HANA helps clarify the unique capabilities of HANA's search functionalities.
