+Currently, ikiwiki indexes the "title" and "link" fields of a page
+using the prefix "Z".
+This is incorrect.
+"Z" is for stemmed terms,
+which xapian inserts itself.
+Furthermore, the custom field "LINK" should use the "X" prefix.
+(This is according to the [xapian-omega documentation] [xapian].)
+
+I have a [patch][] that fixes this.
+Once it is applied,
+the wiki should be rebuilt to fix the search index.
+
+What problems does the current behaviour cause?
+Consider the [[tags]] page.
+ikiwiki indexes the term "ZStags" for its title.
+xapian stems this and also indexes "ZZStag".
+(Notice the additional "Z".)
+Now when [searching for "title:tags"] [search],
+xapian stems this and searches for "ZStag",
+and so only finds pages which were indexed by _ikiwiki_ with "ZStag"
+(i.e. those pages with the singular "tag" in the title).
