RE: None Re: Pupose of repeat the search with the omitted results included.

[Adam Burr]

What is the real purpose of filtering??? As I understand it the intention of this feature is to try to improve the relevance of the displayed results by filtering out results which are very similar to each other. When it detects many results that are highly similar it only displays 2 of them by default. This makes room on the first page for other results.

E.g. Imagine if you index contains a document which is highly relevant to the user's query plus 9 other old versions. If it weren't for this filtering feature then the results displayed would just be 10 near-identical hits. Instead we get one hit, then an indented similar one, and then 8 unrelated hits from other parts of your index.

To put it another way the filter is trying to prevent one type of result from dominating the results which would badly affect users looking for something else.

You can turn off this feature using the "filter=" query parameter e.g. "filter=0" turns it off altogether. There are also other values available if you read the search API documentation.

Hope this helps.

Regards,

Adam.

That feature is called Filtering. The documentation is here:
