Is there a Stack Exchange API allows research on the body?

Question

I want to use the Stack Exchange API to perform research on the question/answer's body but it seems impossible.

Is that the case? If not, how do I go about doing it?

Answer 1

In order to access the body of a post, you need to create a filter that includes this information. You create a filter using the /filters/create method:

http://api.stackexchange.com/2.0/filters/create?include=question.body;answer.body

The response from that URL will look something like this:

{
  "items": [{
    "filter":"!9Tk5izFWA",
  ...
}

As you can see, the new filter is identified by the string !9Tk5izFWA. You need to then pass this as the filter parameter to any request that you want to obtain the post body on.

Example:

http://api.stackexchange.com/2.0/questions?site=stackoverflow&filter=!9Tk5izFWA

---

Edit: upon further clarification, the method you are looking for is /search. The example would now become:

http://api.stackexchange.com/2.0/search?site=stackoverflow&filter=!9Tk5izFWA&intitle=java

This example will search for all questions that contain the string "java" in the title.

Answer 2

It's impossible to search in the body with the api stackexchange.
