Fixed typos in boolean fulltext search text.

MySQL considers both your hostname and user name in identifying you

because there is little reason to assume that a given user name belongs to

the same person everywhere on the Internet.  For example, the user

@code{bill} who connects from @code{whitehouse.gov} need not be the same

person as the user @code{bill} who connects from @code{microsoft.com}.

@code{joe} who connects from @code{office.com} need not be the same

person as the user @code{joe} who connects from @code{elsewhere.com}.

MySQL handles this by allowing you to distinguish users on different

hosts that happen to have the same name:  you can grant @code{bill} one set

of privileges for connections from @code{whitehouse.gov}, and a different set

of privileges for connections from @code{microsoft.com}.

hosts that happen to have the same name:  you can grant @code{joe} one set

of privileges for connections from @code{office.com}, and a different set

of privileges for connections from @code{elsewhere.com}.

MySQL access control involves two stages:

This query retrieved all the rows that contain the word @code{MySQL}

(note: 50% threshold is gone), but does @strong{not} contain the word

@code{YourSQL}.  Note, that it does not auto-magically sort rows in

derceasing relevance order (the last row has the highest relevance,

decreasing relevance order (the last row has the highest relevance,

as it contains @code{MySQL} twice). Boolean fulltext search can also

work even without @code{FULLTEXT} index, but it would be @strong{slow}.

... word ``apple'', but rank it higher if it also contain ``macintosh''

@item +apple -macintosh

... word ``apple'' but not ``macintosh''

@item +gates +(>hell <bill)

... ``hell'' and ``gates'', or ``bill'' and ``gates'' (in any

order), but rank ``gates to hell'' higher than ``bill gates''.

@item +apple +(>pie <strudel)

... ``apple'' and ``pie'', or ``apple'' and ``strudel'' (in any

order), but rank ``apple pie'' higher than ``apple strudel''.

@item apple*

... ``apple'', ``apples'', ``applesause'', and ``applet''

... ``apple'', ``apples'', ``applesauce'', and ``applet''
