Not a bug, but perhaps hard to field from the docs.
To mandate each line as a loop-code, instead of space-separated values,
define mv_search_line_return, or the lr=1 parameter. Here is an example for
the simple demo:
<PRE>
<U>Loop</U>
[loop search="
se=Mona
sf=title
rf=title
"]
-->[loop-code][/loop]
<U>Loop lr=1</U>
[loop search="
se=Mona
sf=title
rf=title
lr=1
"]
-->[loop-code][/loop]
</PRE>
-->Mona
-->Lisa
-->Mona Lisa
is what should appear.
This allows you to loop over searches that will return multiple
values for a single field. I find it useful for selecting a database
record based on more than one field or on things other than the key.
