[Exist-open] Query: XQuery/Keyword Search in eXist 1.4

[Sidharth A. <sag...@as...>]

The documentation in page : *
http://en.wikibooks.org/wiki/XQuery/Keyword_Search ,* seems to be for eXist
1.3 version.
I am trying to do the same thing in eXist 1.4.
What all changes i need to make to get the same result.

I have made the following changes in the search.xq code, as was stated in
one of the thread.

1. kwic.xql can be referenced now as follows: BEFORE: import module
namespace kwic="http://exist-db.org/xquery/kwic" at
"xmldb:exist:///db/test/kwic.xql"; NOW: import module namespace kwic="
http://exist-db.org/xquery/kwic";

2. replace the "&=" syntax with lucene search syntax: BEFORE: let
$search-string := concat('$scope', '[. &= "', $filtered-q, '"]') let
$hits := util:eval($search-string) NOW: let $hits :=
ft:query($search-string)

3. hit scoring is now built-in to lucene: BEFORE: let $sorted-hits := for
$hit in $hits let $keyword-matches := text:match-count($hit) let
$hit-node-length := string-length($hit) let $score := $keyword-matches div
$hit-node-length order by $score descending return $hit NOW: let $sortedhits
:= for $hit in $hits order by ft:score($hit) descending return $hit
I am getting this error when i call "
http://localhost:8080/exist/rest/db/test/search.xq"
ERROR: Unexpectedly received 1 parameter(s) in call to function
'ft:query()'. Defined function signatures are: ft:query($nodes as node()*,
$query as item()) node()*
 [at line 18, column 14]

Any suggestions.

Thanks
