Summary: complex scoring query
Initial Comment:
the following query was running fine a few month ago. however, in the current
version it returns a strange error:
let $nexi := "[about(.//keyword, Musik)]"
let $offset := 0
let $limit := 20
let $query_v := concat("//video", $nexi)
let $opt := <TijahOptions ir-model="NLLR" returnNumber="{$limit +
$offset}"/>
let $qid_v := tijah:queryall-id($query_v, $opt)
let $nodes_v := subsequence(tijah:nodes($qid_v), $offset, $limit)
let $query_s := concat(".//segment", $nexi)
let $qid_s := tijah:query-id($nodes_v, $query_s, $opt)
let $uri_s := tijah:nodes($qid_s)/@uri
return <results>
{for $rsc in $nodes_v
let $rsc_seg := $rsc//segme...@uri = $uri_s]
return <rsc uri="{$rsc/@uri}" score="{tijah:score($qid_v, $rsc)}">
{for $seg in $rsc_seg
return <seg uri="{$seg/@uri}" score="{tijah:score($qid_s,
$seg)}"/>}
</rsc>}
</results>

<results><rsc!ERROR: XML Generation: tmp_522 BAT does not have a 9 head.
MAPI = mone...@localhost:42911
QUERY = let $nexi := "[about(.//keyword, Musik)]"
ERROR = !ERROR:
!ERROR: XML Generation: NULL BAT has a 9 head, but tail is NULL.
!ERROR:
!ERROR: xquery_print_result_main: operation failed.
i have not analysed whether it should be called a pathfinder or pf/tijah bug,
but the involved tijah-queries run fine, when executed isolated. the error just
occurs in the last part of the query when new elements are created showing the
query results.
in order to run the query, one needs to index the attached tiny collection. for
instance by using this indexing script modified by the path to the collection
source:
let $collname := "vitalasCollection"
let $dir := "/ufs/henning/work/vitalas/collection/"
let $file := "vitalasIRT10h-normalized2_newh.xml"
return pf:add-doc(concat($dir,$file), $file ,$collname)
<>
let $collname := "vitalasCollection"
let $opt := <TijahOptions stemmer="porter-english"/>
return tijah:create-ft-index($collname, $opt)

Message:
shortest query that leads to the same error message:
let $opt := <TijahOptions ir-model="NLLR"/>
let $qid_s := tijah:queryall-id("//segment[about(.//keyword, Musik)]",
$opt)
let $nodes_s := tijah:nodes($qid_s)
return
for $rsc in $nodes_s
return <seg uri="{$rsc/@uri}"/>

Message:
using peter's MIL logging script i created a log-file in order to see,
where exactly the error occurs.
apparently, it happens very much at the end of the query execution during
these lines:
if (not(isnil(a0002))) {
ERROR (a0002);
} else {
}
however, the output generated earlier seems corrupt as well.
