[(search group=item if="inlist {p2} {info.categories::{+p}}"
template="title")]
for every page in group 'item', if the second part of the current
pagename is in the cvs list '{info.categories::{+p}}', apply the
template "title".
'title' is a built in template
{info.categories::{+p}}
is a page-variable. See documentation and example below.
Let us have the following pages:
category.fruit
category.mammals
item.dog <empty>
item.cat <empty>
item.apple <empty>
item.pear <empty>
info.categories
<code>
item.dog: mammals
item.cat: mammals
item.apple: fruit
item.pear: fruit
</code>
if you open the page categories.fruit, the search function will find
all the item pages, and find that:
'fruit' is not inlist info.categories::item.dog
'fruit' is not inlist info.categories::item.cat
'fruit' is inlist info.categories::item.apple
'fruit' is inlist info.categories::item.pear
and will thus return 'item.apple,item.pear' formatted with template
'title'.
