AUTOCOMPLETE

The following procedures and function in the DBMS_SEARCH package enable implementation of Autocomplete. Autocomplete is a search-as-you-type technique used for improving query productivity. It finishes a term or phrase based on partial input by predicting and suggesting possible completions of a word or query. This leads to a faster, more user-friendly search experience by helping to find items even with incomplete or partially mistyped queries.
