Hello,
I have a questions with limitations/restrictions that are around for
full text search.
I have a field with data like XY-11443;. and I need to find the

all was working before the task switched hands.
The basic query is
select * from metadata where match(type) against ('+XY-11443' in boolean
mode);
This query spins through all of my records and gives no results.
However, if I remove the XY- and just do ('+11443' in boolean mode) I
get an immediate and correct result.
I believe there is something going on with the '-' in the string that is
causing trouble - like maybe a stop word or something - but can't find
exactly what is going on and more importantly HOW TO FIX IT
Any help would be awesome!

Hi!

Hello,
I have a site that I'm trying to implement a search engine on existing and
archived news stories on a medium text datatype in a database.
I read the documentation and got it running, but unless I missed something
it's not doing what I want it to do.
For example, if I put in the keywords [Alpine Fire], it will return all
stories with Alpine Fire in it. That is what I want, but if there's
another story about a fire, the search will return that also. Or if
there's a story about an incident on Alpine street, that will also
be returned.
What I want is only stories that contain the keywords [Alpine Fire]. Is
there a way to do that with a full text search? I'd rather not have to
do a search using [LIKE '%Alpine Fire%'] because that doesn't seem like
the most efficient way to do a search.
chris
Until 4.0 MySQL will have no native support for phrase searching (it's what
you need).
You can work around this with
SELECT ... WHERE MATCH col AGAINST ('Alpine Fire') and
col LIKE '%Alpine Fire%'
This should be pretty fast, as the main filtering would be done by MATCH
(be sure to verify this with EXPLAIN, though).
But even without LIKE, stories about 'Alpine Fire' will have higher
relevance and will be returned first, so simple LIMIT will help to
distinguish between relevant (about 'Alpine Fire') and not relevant
(about Alpine street or about a fire) stories.
That's how most search engines work.
Regards,
Sergei

Re: Full Text Search Question
To do a full word match like you are wanting, you would need to break up the sql query to do this: ... WHERE field LIKE "%word1%" AND field LIKE "%word2%" ... That is how you have to do it if you are not using one of the latest 3.23 versions of mysql. If you have a newer version of mysql, check out this page for more info http://www.mysql.com/doc/M/y/MySQL_full-text_search.html On 4/3/01 11:07 AM, "Oson, Chris M."

Re: Full Text Search Question
Oson take a look at mysql documentantion. You can do this with match
against.
A IR system is somewhat different than a DB. But mysql is both an IR and
a DB.
