For a university search engine project, I am using MonetDB with Tijah extensions. I've got a list of nodes, returned from a search string:
let $qid := tijah:queryall-id($nexi)
let $nodes := tijah:nodes($qid)
$nodes
now contains a list of elements, e.g.:
<book>Design Patterns</book>
<book>AntiPatterns</book>
I can calculate and return the scores for this list with the following FLOWR expression:
for $book in $nodes
let $score := tijah:score($qid, $book)
order by $score descending
return <book score="{$score}">{$book/title}</book>
However, I want to use the list of nodes in a new search query. To do this, I have to generate a string from this list with the following formatting:
Design Patterns {0.2937} Antipatterns {0.43984}
In this formatting the scores (returned by tijah:score
and the names are combined. I wanted to generate this string with a recursive function, but the MonetDB Algebra engine I need to use doesn't support recursive functions.
Can I generate the same result with a non-recursive (possibly FLOWR) expression?
