For OpenSearch, it's possible to define a search engine whose first search result is numbered "0", and first page of search results is numbered "0", too. This is done using the "indexOffset" and "pageOffset" parameters on the Url element of the OpenSearchDescription document. The default for each is "1".

Even when the attribute is set in the OpenSearch description, Firefox requests the first search results with startIndex = 1.

Reproducible: Always

Steps to Reproduce:
1. Create an OpenSearch description with indexOffset = 0.
2. Add the description to Firefox.
3. Do a search.

Actual Results:  
The startIndex parameter is set to 1.

Expected Results:  
The startIndex parameter should be unset or set to 0.

Leaving out the startIndex parameter template from the OpenSearch description gives normal functionality. Since Firefox doesn't do paged or indexed searches, it's a moot point, but IWBNI the software would follow the standard.

Yeah, we don't support indexOffset or pageOffset, because when I was implementing the OpenSearch support that parameter wasn't yet finalized.

In the renewal MDC, Search engine( http://developer.mozilla.org/@gui/opensearch/description ) have indexOffset attribute set to "0".
Then if use this search engine, Search results don't show 1st hit page always.

Not totally sure we need this, since it hasn't been requested by search engines. This could possibly be removed from the spec, though it would be interesting to know if other browser support this as well or not.
