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).
