I could not find answer to my question anywhere. I have done a research but without any luck.

Let’s say that we query a following statement:

SELECT `id`, MATCH(`name`,`content`) AGAINST ('some keywords') AS `score` FROM `pages` WHERE MATCH(`name`,`content`) AGAINST ('some keywords')

Is MySQL going to give me a score according for the whole table pages, will it scan for all other records there? Or is it going to give me a score just considering a row with columns supplied (name and content) in our case.

    Yes it uses the keyword frequency in other rows too. Taken from MySQL Fulltext Search, the formula is:

    w = (log(dtf)+1)/sumdtf * U/(1+0.0115*U) * log((N-nf)/nf)

    Where:

    dtf is the number of times the term appears in the document sumdtf
    is the sum of (log(dtf)+1)’s for all terms in the same document U
    is the number of Unique terms in the document N is the total
    number of documents nf is the number of documents that contain
    the term
