Build a fully functional text search engine on top of native Pinot indices, allowing exact matches, prefix and suffix matches, substring matches and regular expressions.

Performance of the text search component (automaton, matcher and FST) should be comparable or better than Lucene's FST, matcher and automaton.

Build the engine using core Pinot capabilities and have it deeply integrated with Pinot's core components

Allow the library to be reusable across Pinot.

Allow the library to be extensible without requiring application changes
