structure is essentially without rivals as the most efficient structure for supporting ad hoc text search To create a new index for a table, you use the CREATE INDEX statement as follows: CREATE INDEX index_name ON table_name (column1 [,column2, Capture For example: SELECT SUBSTRING (‘SUBSTRING Examples’, 1, 9); In certain scenarios, we have columns that store large strings Key && item Expand Databases, and then expand the database that contains the full-text index Code language: SQL (Structured Query Language) (sql) In this example, we created a new table named articles that has a summary column with the data type is TINYTEXT For a property with both ID and FTS indexes, where the ID index is the default, force the use of the FTS index The inverted index supports efficient full-text searches on natural language text collections A field type defines the analysis that will occur on a field when documents are indexed or queries are sent to the index The inverted index supports
