May I suggest? Probably it will be more useful to create a separate
table with one column and one raw and store current documents number
there:
CREATE TABLE ndocs (ndocs int);
Then after every reindexing run this:
DELETE FROM ndocs;
INSERT INTO ndocs SELECT count(*) FROM url WHERE .....
You may write a script which will run indexer and then
execute these queries. Or you may also add these queries execition
into crontab.
Then in search.php use:
SELECT ndocs FROM ndocs
to get last calculated doc number. It will be much faster when
count(*) with WHERE clause.
