How to use FTS in SQLite with Monotouch for iOS

由 烈酒焚心 提交于 2019-11-29 08:57:00
I'm looking to build an iOS app using Monotouch that has a rather large sqlite db full of text. I need to provide fast searching over this text. My best solution right now is the FTS module (preferably version 4). I have read that the default instance of sqlite on iOS does not support FTS. If this is true what is the recommended way to build a custom instance of sqlite with Monotouch? Or can this be done at all? I found this site describing how to accomplish this with xcode, but it is not clear how I would accomplish with Monotouch. http://longweekendmobile.com/2010/06/16/sqlite-full-text

问题 Is there any way to search for a particular string in a column? I want to search like SELECT * from email_fts WHERE email_fts MATCH 'to:"a@b.com" OR from:"c@d.com"' Thanks in advance, Manoj 回答1: Make sure you create proper FTS columns in the FTS index: CREATE VIRTUAL TABLE email_fts USING fts3(subject, body, "to", "from"); And then you can search individual FTS columns: SELECT rowid FROM email_fts WHERE "to" MATCH 'a@b.com' UNION SELECT rowid FROM email_fts WHERE "from" MATCH 'c@d.com' EDIT :
