Hallo! http://en.wikibooks.org/wiki/Special:Search?search=lrm&fulltext=Search is displaying 19 results. It displays also: *Results 1-20 of 29* and links as 2 : http://en.wikibooks.org/w/index.php?title=Special:Search&search=lrm&fulltext=Search&offset=20&limit=20 Next » : http://en.wikibooks.org/w/index.php?title=Special:Search&search=lrm&fulltext=Search&offset=20&limit=20 Both are empty pages. Regards Reinhardt [[user:gangleri]]
the links disapeard It shows *Results 1-20 of 20* but there are only 9 results
Created attachment 1312 [details] Example search returning incorrect numbers/listing. I don't know if this is connected, but on Wikipedia I've just tried a search, which returns 'Results 1 to 8 of 8', but only shows a single result. I also received similar 'incorrect' results for a couple of other searches. I have attached a screenshot. (Using firefox 1.5)
Created attachment 1313 [details] A second example Here is a second example. It shows '1 to 20 of 51', but only lists 7 results. The links for subsequent pages are present, but when clicked they return "Sorry, there were no exact matches to your query."
Already known issue. The total count is pre-namespace filtering. Doing namespace filtering in Lucene is too expensive.
Can we change the text to something like the following: "Showing items $1 to $2 out of $3 results found across all namespaces. Only showing results in the '$Namespace' namespace" If it can't be fixed, then we should acknowledge and work round the problem rather than ignore it.

If the current page contains no results after namespace filtering, there seems to be no way to get to another page that might have results. See, for example, http://en.wikipedia.org/w/index.php?title=Special: Search&search=Francis+Ford+Coppola&fulltext=Search&ns10=1&ns11=1&offset=0&limit=20 . First page has one result, second page has no results and no way to get to third or other pages (without simply editing the URL).

Can't you just fetch 21 results, only show the 'next' button if the 21st result exists and not display either that result or the total count (or use language like 'Approximately')?
21? Or 22? Or 23? Or 23,000? How many will you have to fetch to get 20 viewable results? There's no way to predict that ahead of time.
I think ekb87ds02 was suggesting to fetch 21 viewable results, and then show 20, and interpret the remaining one as "there are more results". This is fine, however, with some namespace filter caching we could actually get the exact count.
Fixed in Lucene Search 2. The queries are always either filtered by cached filters, or rewritten so that they return the articles from given namespaces. So, the number of hits should always be correct.
