MySQL fulltext with stems

问题

I am building a little search function for my site. I am taking my user's query, stemming the keywords and then running a fulltext MySQL search against the stemmed keywords.

The problem is that MySQL is treating the stems as literal. Here is the process that is happening:

1. user searches for a word like "baseballs"
2. my stemming algorithm (Porter Stemmer) turns "baseballs" into "basebal"
3. fulltext does not find anything matching "basebal", even though there SHOULD be matches for "baseball" and "baseballs"

How do I do the equivalent of LIKE 'basebal%' with fulltext?

EDIT:

Here is my current query:

SELECT MATCH (`title`,`body`) AGAINST ('basebal') AS `relevance`,`id` FROM `blogs` WHERE MATCH (`title`,`body`) AGAINST ('basebal') ORDER BY `relevance` DESC

回答1:

I think it will work with an asterisk at the end: basebal*. See the * operator on this page for more info.

See This link.. Stemming is not installed BY default in MySQL but you can install it your self..
