Hi Lee,
Thanks for these code samples. I need to allow moderately complex
queries using the operators and, or, not, near unordered and near
ordered ... and potentially an indicator to boost the weight of
selected terms. I wrote the little parser I have in C# because I
really wasn't sure how to approach it in XQuery, but taking a look at
these I can see how it might be put togther.
Thanks again!

Hi Mattio,
The answer depends on how simple or complex you need your query to be. A
simple approach to satisfy just the above could be:
(Assume $query is your external variable)
let $query := "view, contents"
return cts:search(//LINE, cts:and-query(tokenize($query, ", ")))
This assumes you always want to AND your keywords.
You could pass in XML representing your query and parse it:
define function get-query($query as element(query)) as cts:query {
let $query-body := $query/*
return
typeswitch($query-body)
case element(and) return process-and-query($query-body)
(: process or query :)
default return error("Invalid query type")
}
define function process-and-query($and-element as element(and)) as
cts:and-query {
cts:and-query(data($and-element/word))
}
let $query :=
<query><and><word>view</word><word>contents</word></and></query>
return cts:search(//LINE, get-query($query))
You can use xdmp:unquote() to turn your xml sting passed in via your
external variable into a document node.
You might even want to take a look at:
