how can I enter a date restriction when using the Google Search API?

I'm wanting to use the Google Search API and find results based on the fact that they are only a day old. I can do this through the Google search engine but I can't seem to find a way to do this by using the API.

my code: $googleFullURL = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=large&start=$searchIndex&lr=lang_en&filter=0&q=$searchTerms";

I tried using "&tbs=,qdr:d" at the end of my se开发者_C百科arch which is what the search engine appends at the end of the URL when restricting to a date range but this seems to not be working.

thanks

You want to use the dateRestrict parameter which is a string.

Restricts results to URLs based on date. Supported values include:

• d[number]: requests results from the specified number of past days.
• w[number]: requests results from the specified number of past weeks.
• m[number]: requests results from the specified number of past months.
• y[number]: requests results from the specified number of past years.
