Hi there.

I'm learning to build a web site using php and postgresql/mysql on Linux platform. I want to add google search on my site. How to do it. Please show me the right direction.

go to google.com and there are link with code you can just copy/paste to add the google search banner to your site.

Well, on the google site they have an api that lets you add complex google search functionality to your website. However, at its simplest, a google search just retrieves the URL with the format:

http://www.google.co.uk/search?hl=en...G=Search&meta=

where in this example my two search words were steve and dave. Google just joins them with a + sign. So, at the most basic level you need a box to take search words from your visitors, form them into the correct syntax (i.e. join them with + signs and anything else google does (what if people specify + or - to include or disregard words from searches?) and then pop it into the middle of that URL and redirect people to that. If you don't want them actually redirected to google then you'll have to retreive the page and do some parsing of your own to get the results for you to display in your own way.

Aha...I looked but couldn't find this...

seems they took it off of their site, but found this link for you:

enjoy. seems they have a bit of html at the bottom of the page that will custom make a google search banner for your site with your URL.

Moved to programming as it is kinda of a programming issue...
