问题
I'm using mysql's built in boolean fulltext features to search a dataset. (MATCH... AGAINST syntax).
I'm running into a problem where keywords that are in MySql's default stopwords list are not returning any results. For example, "before", "between", etc.
There is (I think) no way to disable MySql's stopwords at runtime. And because I am hosting my website on a shared server (DreamHost), I dont have the option of recompiling MySQL with stopwords disabled.
I'm wondering if anyone has any suggestions on ways around the above problem? (Without upgrading to a VPS or dedicated system)
Thanks in advance for your help,
Travis

I had this issue and did a google search coming across this post (over a year later) I am on a shared host as well and was pulling my hair out over the stop words set in mysql. I found a workaround that has been working perfectly for me, hopefully it can be of some use to others as well.
You can also use the REGEXP command to match a search term within your table.
SELECT * FROM table WHERE column REGEXP 'searchterm'
How I implement it is by first doing the MATCH AGAINST syntax, if the count = 0 I do the REGEXP instead giving my users more results. Better than no results at all due to stop words and minimum lengths.

Forget it, the change of mysql full-text setting require a restart
details - http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html
note that Dynamic column is marked as NO for ft_stopword_file
However, is no harm to check with your hosting service provider...
If it do restart for you, you can use the following to repair your table full-text
mysql> REPAIR TABLE tbl_name QUICK;
