Even if I use the stock example from the web page, with only 2 columns, and the exact schema from the example, I get the same result.
I'm wondering if it is a bug in the example code on the website (ie the source code has moved on, invalidating an example based on old code), or it's just something in turning their c code example into a full extension that I didn't do right. From the extension's source code: nCol = aMatchinfo[1]; if( nVal!=(*1+nCol*) ) goto wrong_number_args; So, it should scale with the number of columns. (I would hope it's not hardcoded to a set number of columns!) -------- Original Message -------- Subject: Re: [sqlite] FTS4 code from the website From: Dan Kennedy <danielk1...@gmail.com> Date: 6/29/2011 11:25 PM > On 06/30/2011 10:31 AM, Ryan Henrie wrote: >> Reference Page: http://www.sqlite.org/fts3.html#appendix_a >> >> At the bottom of the page, there is a sample c file to calculate the >> rank, and a FTS query to use it.
