Please show me where I'm wrong with this query:
SELECT * FROM `pages` WHERE MATCH ( abstrak) AGAINST ('+"prove"' IN BOOLEAN MODE)
doesn't get 'proves', when I want is it gets 'proves'.
Try this:
SELECT * FROM `pages` WHERE MATCH ( abstrak) AGAINST ('prove*' IN BOOLEAN MODE)
This would match all words that start with prove, including proves.

I am trying to make a query where I select all the rows that do not contain a specific word, for this I have a fulltext type index in this column, try the following bolt works:
SELECT *
FROM products
WHERE MATCH(title) AGAINST(' -Dolo' IN BOOLEAN MODE)
So how can I perform this search?
If I have understood you correctly you want to find all the rows from the table that do not contain a word'Dolo'.
Well you can use NOT operator for that.
SELECT *
FROM products
WHERE NOT MATCH(title) AGAINST('Dolo');
Here is a DEMO.
Also, you can use it like this(because as the OP has asked: "if the whole word is "dolorem", would this query work?"):
SELECT title as Title
, MATCH(title) AGAINST('Dolo*' IN BOOLEAN MODE) as Score
FROM products
WHERE MATCH(title) AGAINST('Dolo*' IN BOOLEAN MODE) = 0;
* is a wildcard.
Other signs are described here: https://dev.mysql.com/doc/refman/8.0/en/fulltext-boolean.html
Here is the DEMO for the second example.
I added a FULLTEXT index to a table like so:
ALTER TABLE TEST ADD FULLTEXT(name, descrip, notes);
The TEST table has 100 rows. I updated the descrip column with 'branch' in one row and 'Branches' in another row.
Then I run
SELECT * FROM TEST WHERE MATCH(name, descrip, notes) AGAINST ('branch' IN BOOLEAN MODE);
The result returned only rows that contain 'branch'. 'Branches' is not included in the result, even though it is comprised of the word that was searched. How to include 'Branches'? I want to avoid using LIKE.
In boolean mode you can use a wildcard:
AGAINST ('branch*' IN BOOLEAN MODE);
Here goes your query. You need to use wildcard.
SELECT * FROM TEST WHERE MATCH(name, descrip, notes) AGAINST ('branch*' IN BOOLEAN MODE);
SELECT * FROM `video` WHERE `title` LIKE '%next%'
or
SELECT * FROM `video` WHERE `title` LIKE 'next'
i can get results from the searches which are written above.
but; i cannot get any result with the code which is written below.
SELECT *, MATCH(title) AGAINST('next') AS relevant
FROM video WHERE MATCH(title) AGAINST('next' IN BOOLEAN MODE)
ORDER BY relevant DESC
how can i get a result from the search of "next" word via "fulltext-search" ?
I had the next problem and I found the answer here:
http://dev.mysql.com/doc/refman/5.7/en/fulltext-stopwords.html
There is in fact a list of stop words that will not be returned when you try to do your fulltext search
I am trying to enhance a third part (awesome) django framework named django-watson and I currently need to make my way through a so far unknown mysql option, the MATCH (...) AGAINST (...).
So, I already know how to retrieve an exact phrase, which is doing:
SELECT *
FROM patient_db
WHERE MATCH ( Name, id_number )
AGAINST ('"exact phrase"' IN BOOLEAN MODE);
An I also know how to retrieve results that contain words from a list:
SELECT *
FROM patient_db
WHERE MATCH ( Name, id_number )
AGAINST ('+keyword1 +keyword2' IN BOOLEAN MODE);
But I need a third option, which is mixing the two above quoted. I'd like to do something like the google search: "exact phrase" +keyword1 +keyword2.
_PS: when I search for "exact phrase" -keyword1 it works exactly as desired _
Any Ideas?
Try this.
SELECT *
FROM patient_db
WHERE MATCH ( Name, id_number )
AGAINST ('+keyword1 +keyword2' IN BOOLEAN MODE)
OR MATCH ( Name, id_number )
AGAINST ('"exact phrase"' IN BOOLEAN MODE)
I've heared alot of similar discussion but I havent seen a direct solution.
SELECT * FROM patient_db WHERE
MATCH ( Name, id_number ) AGAINST ('%$term%' IN BOOLEAN MODE);
Isn't there something simple around my '%$term%' I need to do to enable multiple-word searching?
Unfortunately, there is no way to directly say, "I want one of these n words" in a MySQL fulltext query. Your only real option is
SELECT * FROM patient_db WHERE
MATCH ( Name, id_number ) AGAINST ('%$term%' IN BOOLEAN MODE)
OR MATCH ( Name, id_number ) AGAINST ('%$term2%' IN BOOLEAN MODE)
OR MATCH ( Name, id_number ) AGAINST ('%$term3%' IN BOOLEAN MODE)
;
Just curious, but why are you searching a column named id_number for text?
