==Only main namespace is searched by default==
The search only applies to the main namespace (those pages without "MediaWiki:" or "talk:" or "user:" in front). The main namespace contains pages, indexes and other content-oriented book pages. To search the other namespaces check or uncheck the tickboxes in "Search in namespaces" box found at the bottom of a search results page. Depending on the browser, a box may still be checked from a previous search, but without being effective any longer! To make sure, uncheck and recheck it.
