Manu, et al,
The database in alenet.com is rather tiny (about 28 docs, as you
mentioned). I developed the procedure for a intranet with some 5000
records. It is working fine. It has some 20+ clients that are
constantly hitting the database. The server is a desktop (nothing out

Curt, et al:
You just described my procedure! I do exacly that, plus, I also save a
soundex or metaphone code for each word so I can check spelling and
closest matches.

I used a variant of this scheme a time ago and it worked well though I had
not reached 2 000 records.
I separated the words using strtok().

PD: How large is the http://www.alenet.com DB; I searched the word 'the'
(which is likely to be in every english doc) and it returned only 28 docs.

2. save in the keyword table the non repeating words in the array with a
reference to the original document, for example the document id.
3. Then, if you want to search for, let say, people you will do:

Subject: [PHP] Slow searches in large database

Hi!
I think that you will need a keyword table to speed up this procedure.
The basic idea is to create an index of words in your fields,
therefore you will not use like but = making things run much, much
faster.
The steps for doing this are:
1. Every time you save a record in the table
Rather than searching every field for every search I usually provide a
select drop down or checkbox that allows the user to indicate what
information they are searching, then only hit those fields in the SQL
query.
MySQL is fast for simple queries but it doesn't scale well with larger

Basically, is there anything that anyone can immediately suggest that

1. You could try changing 'docs.*' to a verbose
Start by checking the MySQL docs to find out if indexes are used with IN
and LIKE especially as the latter is using wildcards. I suspect not.
Given that you are essentially performing a sequential read of the
database and checking on all these fields your performance is remarkably good.
