Dear Experts,

I have the following

$str_phrase = htmlentities($_GET['phrase']);

which is then used in a mysql query like so

where match (col1, col2) against ('$str_phrase')

But this does not let me use the + and - keys on the web page.  For example

Lets say the user types in the following

I am searching for information about +water -sand

It seems to ignore the + and - in that string.

How do I stop ignoring them?

than you have to simulate it: seperate plus-phrases from minus-phrases:

where match (col1, col2) against ('$plusPhrase')
and not match(col1, col2) against ('$minusPhrase')
