Help with AND/OR Search

Question

Hi all,
I'm setting up an 'Advanced Search' feature using a filter function and need some help with the logic - seem to be suffering a brain fade...
There's a search form with (let's say) 4 different options:  Name, Description, Price, Features.
I want the user to be able to fill in all or none of the fields and return the matching results.
I can do an OR function like this:
if(Name.match(regx1) || Description.match(regx2) || Price .match(regx3) )|| Features .match(regx4){
     return true;
}else{
     return false;
I know I could change the "||" to "&&" - but I need to do this only if there's something to search...
The only way I can think of doing this at the moment is to write a bunch of 'if statements' with all permutations - eg:
if(Name && !Description && !Price && !Features){
     //match Name only
}else if(Name && Description && !Price && !Features){
     //match Name & Description
}else... you get the idea
Thanks for your help!
Cheers

hey Madhav,
Thanks for the pointer.  I haven't used a bitwise AND Assignment before...
When I write some code like below I get a compile error saying "Implicit conversion of type Boolean to an unrelated type Integer"
From what I understand, 'criteria' should remain true only if the comparator is true.  But why do I get a compile error?
Do you know what I'm doing wrong?
var criteria:Boolean = true;
var nameMatch:Boolean = false;
if(name){
     if(name.match){
          nameMatch = true;
if(name){
    crieteria &= nameMatch;  // compile error here
thanks for your help!
