This is the full function. The $doctype corresponds to the root element of the file. So if I have files that are concepts and tasks and I say search in doctype concept, no task will be returned.
<concept><title>concept blah</title><conbody>More blah</conbody></concept>
<task><title>task blah</title><taskbody>A bunch of steps...</taskbody></task>
*.* happens when the keyword section of the query is an empty string. We assume that the user wants all results for the specified doctype. If no doctype (empty string) is specified, we assume they want the entire library.
In 8.5.2, I get 0 item found when I search for keywords = ''
declare
function search:search-all($doctype as xs:string, $keywords as xs:string, $operator as xs:string, $lang as xs:string) as node(){
let $keywords :=
if (normalize-space($keywords)='')
then '*'
else $keywords
let $words := tokenize(normalize-space($keywords), ' ')
let $wild-words := for $word in $words
return concat($word, '.*')
let $first-words := if (count($words) > 1)
then string-join($words[position()!=last()], ' ')
else ''
let $last-keyword := tokenize(normalize-space($keywords), ' ')[last()]
let $wild-keywords := if (string-length($last-keyword) > 3)
then concat($first-words, ' ', $last-keyword, '.*')
else ''
let $all-wild-keywords := tokenize(normalize-space($wild-keywords), ' ')
let $search-subset :=
if ($doctype = '')
then db:open($lang)/*
else db:open($lang)/*[name()=$doctype]
let $search-result :=
if ($operator = 'and')
then $search-subset[(descendant::title[1] contains text ({$wild-words} all using wildcards weight {2})) or (. contains text ({$wild-words} all using wildcards weight {0.5}))]
else $search-subset[(descendant::title[1] contains text ({$wild-words} any using wildcards weight {2})) or (. contains text ({$wild-words} any using wildcards weight {0.5}))]
let $ordered-results := for $x score $s in $search-result
order by $s descending, $x/title ascending
return $x
(: Adding no result in options because Safari 9.1.1 doesn't always respond to :empty
no longer being empty after a $.get :)
