Given the URL (single line):

How can I extract the following parts using regular expressions:

The best I could come up with is to produce a matrix of sums of each pair, and then merge the rows together, a-la merge sort. I feel like I'm missing some simple insight that will reveal a much more efficient solution.
My algorithm, in Haskell:

Maybe you should try including a fourth column, stating the table it came from, and then order and group by it:
SELECT A,B,C, "query 1" as origin FROM table WHERE field LIKE 'query%'

SELECT A,B,C, "query 2" as origin FROM table WHERE field LIKE '%query'

@Patrick you are assuming calling setValueInVector( v, idx ); at the end of the second loop is OK. If the code is to be identical, logically, it must be rewritten to somethng like this:

Using ints is generally better than using shorts because java uses 32-bit values internally anyway (Even for bytes, unless in an array) so using ints will avoid unnecessary conversion to/from short values in the bytecode. |
If you're reading TPOP, you will next see how they make this search many times faster with different data structures and algorithms.
But you can make things a bit faster by replacing things like

with
char **p = a;

Run it through the query analyzer and see what the query plan is. My guess would be that the double root (ie. %ae%) searches are causing it do do a table scan when looking for the matching rows. Double root searches are inherently slow, as you can't use any kind of index to match them usually. |
