Hello,

Is there any implicit/explicit ranking mechanism for the results obtained using API for full text search?

example:

http://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=... http://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=Institution&format=xml

If possible, can some one throw some light on the ranking?

Thanks,

Best Regards

The earlier it appears, the more relevant it is expected to be, although the way relevance is determined is something internal by the search backend being used.

When more than one results are returned they are ordered by title, therefore the backend ranking is corrupted. Is there anyway around this, besides asking for an output size of 1 and making repeated queries with successive offsets?

It looks to me like the API returns them ordered by ranking, compare [1] and [2]. It may be that whatever you use to parse the API return is reordering them.
