Version 1 Yahoo! Local Web Services : collectionSearch
The Yahoo! Local collectionSearch service enables you to search for public collections created with the Yahoo! Local Collections service, through a REST-like API. With this web service you can get a list of collections based on specific criteria, including the name of the user who created the plan. Only Collections that have been defined as public can be retrieved using Yahoo! Local Collections Search. Use the information from this search to retrieve more information about a collection with the getCollection service.

Samples & Examples
You can search for public collections containing a specific keyword with the query parameter. The collection's title, description and tags are searched:
You can restrict the search to a city using the city parameter. The location of items in the collection is searched to limit to this city
?appid=YahooDemo&query=pizza&city=san+jose
You can also search for collections created by a specific user with the username parameter:
?appid=YahooDemo&username=ylocal_team
Your request may return a large number of Collection results; use the results and start parameters to determine how many results you get back and from which result you want to start the display. By default, the response returns ten results, starting from result 1. The results parameter indicates how many Collection results to return. So, for example, to return twenty results per request, use this request:
?appid=YahooDemo&query=pizza&results=20
Use the start parameter to start the block of results from some result number other than 1. So, for example, the previous request returned the first 20 collection results. To get the next 20 in the list, use the start parameter with the value 21:
?appid=YahooDemo&query=pizza&results=20&start=21
To get a list of collections containing the phrase "mardi gras": (the first ten are returned):
?appid=YahooDemo&query=mardi+gras
To get a list of collections containing the phrase "mardi gras": (the second 20 are returned):
?appid=YahooDemo&query=hamburger&results=20&start=21
To get a list of collections containing the phrase "thai", and get JSON output wrapped in a callback function called get_collection:
?appid=YahooDemo&query=hamburger&output=json&callback=get_collection
