Sorted_List as C = KEYWORDSI( Character_Expression as C )
A string expression containing words separated by spaces.
KEYWORDSI() returns a sorted list of all of the unique words in Character_Expression. This function is typically used to build an index for full text searching. When you build full text indexes on memo fields and other long character fields, Alpha Five can find a word anywhere within long memos and character fields very quickly, using Lightning Query Optimization. Case insensitive.
