I have a search engine which takes each 'find' or search result from a database, calculates the percentage match, and takes all of the 'find' info and puts it all together into a string, which it adds to an array (each array item is a search result).

Example array:

@records = (".66+5638+copper globe",
            "1.00+1396+the blocks",
            ".33+4055+hunt draw");

As you might have guessed, this database has to do with geographic locations. The strings above are delimited using plus signs. The first item in each string is a decimal resulting from a match calculation ($words_found\$words_searched), which will be multiplied later in the script by 100, and a '%' character will be appended to this string when the match percentage will actually be displayed.

My problem is sorting the percentages. I obviously want the 100% match search results to appear before the 66%'s, 33%'s, or whatever. In older versions of this script, the 100% would come first, the 33% second, and 66% were last, for example.

I tried:

$a = 0; $b = 1;
@records = sort {$b <=> $a} @records;

but since they are strings with a bunch of other stuff in it, the script complained.

I don't want to rip the individual delimited strings apart to sort the array; its already a memory hogging script as it is.

Anyone have any ideas?

Thanks
