Regular Expressions: Is there an AND operator?
I tried the following on http://regexpal.com/ but was unable to get it to work. What am missing? Does javascript not support it?
Regex: (?=foo)(?=baz)
String: foo,bar,baz

Maybe just an OR operator |
could be enough for your problem:
String: foo,bar,baz
Regex: (foo)|(baz)
Result: ["foo", "baz"]
Maybe you are looking for something like this. If you want to select the complete line when it contains both "foo" and "baz" at the same time, this RegEx will comply that:
.*(foo)+.*(baz)+|.*(baz)+.*(foo)+.*
Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:
String to match: "my word"
String to search: "I'm searching for my funny words inside this text"
You need the following regex: /^(?=.*my)(?=.*word).*$/im
Explaining:
^ assert position at start of a line
?= Positive Lookahead
.* matches any character (except newline)
() Groups
$ assert position at end of a line
i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])
m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)

So, you can create a javascript function that:
Example:
function fullTextCompare(myWords, toMatch){_x000D_
//Replace regex reserved characters_x000D_
myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
//Split your string at spaces_x000D_
arrWords = myWords.split(" ");_x000D_
//Encapsulate your words inside regex groups_x000D_
arrWords = arrWords.map(function( n ) {_x000D_
return ["(?=.*"+n+")"];_x000D_
});_x000D_
//Create a regex pattern_x000D_
sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
//Execute the regex match_x000D_
return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);
_x000D_
