Search logics explained

Each logic behaves differently. Please check the practical examples on this page to understand how they work.
The tables below present the major logical difference between the Regular (default) and the Index table engine:
The regular engine cannot use the logic across separate fields for each keyword (title, content, excerpt etc..)
The Index table engine can
OR
Match is found if any of the search keywords is part of the content. It's the least strict of all possible options - it returns many results, finds almost anything.
