It looks like appfunctions.xqy has gone away in ML6.0 and I assume this is why:
The applications generated from Application Builder are considerably different
in MarkLogic 6 than they were in MarkLogic 5. In MarkLogic 6, the applications
use the REST API and do not have any XQuery code. The following are some of the
differences:
*The generated applications use the REST API and are hosted on a REST API
instance.
*The generated applications are now 100% html and javascript; there is no
XQuery code directly in the application.
*Any customizations built in MarkLogic 5 will be lost if you re-generate the
application in MarkLogic 6.
If you have customizations of your generated applications or if you rely on any
of the old application features, then you will need to rework those in
MarkLogic 6. For details on Application Builder and the applications it
generates, see the...
However, when I look at the documentation, it really doesn't give me any direct
examples on how to do custom snippets...
So, in short, I want to do a custom snippet and in the past, I simply created
the snippet module and referenced it in the appfunctions.xqy file. With the
appfunctions.xqy file not being in the /custom/ directory, I'm getting an error
trying to accomplish this in 6.0 according to what I think the equivalent is.
It seems to me that perhaps, under the "Search" tab in App Builder, there is a
"Custom XML Options" button.
So, I added my option there:
<transform-results apply="adv-snippet" ns="/custom/snippet"
at="/custom/dsnip.xqy">
<per-match-tokens>40</per-match-tokens>
<max-matches>5</max-matches>
<max-snippet-chars>200</max-snippet-chars>
</transform-results>
I put this module in the /custom directory:
module namespace dsnip = "/custom/snippet";
import module namespace search = "http://marklogic.com/appservices/search";
at "/MarkLogic/appservices/search/search.xqy";
declare function dsnip:adv-snippet(
$result as node(),
$ctsquery as schema-element(cts:query),
$options as element(search:transform-results)?
) as element(search:snippet)
{
<search:snippet>
{
for $match in search:snippet($result, $ctsquery, $options)/search:match
return
<search:match>
{
if (fn:data($ctsquery/@qtextempty) = "1") then () else
(
<i>{fn:concat(fn:string(fn:node-name(xdmp:eval(xs:string(fn:data($match/@path))))),
": ")}</i>,
$match/node(),<br/>
)
}
</search:match>
}
</search:snippet>
};
I gave it the following persmissions:
xdmp:document-load("/home/tpf106/davids/xquery/snippet/dsnip.xqy",
<options xmlns="xdmp:document-load">
<uri>/application/custom/dsnip.xqy</uri>
<repair>none</repair>
<permissions>{(xdmp:permission("app-user", "execute"),
xdmp:permission("app-user", "read"),
xdmp:permission("app-builder", "update"))}</permissions>
</options>)
I try to deploy and I get a server error...

So, I'm at the end of what I can get out of the 6.0 documentation... Though
it's very possible that I'm missing something...
Thanks,
