问题 I have successfully developed a small iPhone+Monotouch (latest version) application with Monodevelop 2.8, which use a "compiled by me" version of SQLite to enable FTS4. To compile SQLite as static library (libSQLite.a) I used this topic as tutorial: How to use FTS in SQLite with Monotouch for iOS Also I've followed this tutorial to create a Simulator+Device compliant static library: Build fat static library (device + simulator) using Xcode and SDK 4+ Things are working great on the simulator.

For instance imagine I have a full text column containing the words "Steve's Javascript Tutorial - Part One".

问题 I have a column that holds the genre of a movie (up to three specifiers separated by slashes) such as "comedy/romance/adventure." Is there a function or something similar in mysql or php that would allow me to take the genre of a movie and compare it with other genres of other rows and arrange them by likeness?

问题 MySQL can take care of fulltext search quite well, but it doesn't highlight the keywords that are searched, how can I do this most efficiently? 回答1: The solutions posed above require retrieval of the entire document in order to search, replace, and highlight text.
