[MarkLogic Dev General] using search:parse/search:unparse and thsr:query-lookup/thsr:expand

[Treskon, Matthew]

Yes. the output of thsr:expand (which looks right) is not an element (according to search:unparse).

Have you tried thsr:expand()?

Developer Forum,

I am looking to expand our users’ queries using a thesaurus. We are using search:search with an extensive options node. I am looking to avoid having to recreate all parsing structures using string processing. Although string-join may work for simple queries, it becomes considerably more difficult when contending with nested sets (parenthesis), phrases (quotes, beginning and ending), and Boolean/other operators. Subsequently, I was hoping to use search:parse -> thsr:expand/thsr:query-lookup -> search:unparse. However, I am running into mixed-content type and annotation errors. This is basically what I am trying to do:

let $q := <q>"tile drainage" AND (phosphorous OR nitrogen)</q>
let $qparsed := search:parse($q,$OPTIONS)
let $qexpanded := thsr:query-lookup("/myThsrDocs/NALT3.xml",$qparsed)
let $qout := search:unparse(search:parse($qexpanded,$OPTIONS))
return $qout

Is there a way to do this?


So you don’t have to see our options node, $qparsed equals
'
<cts:and-query qtextjoin="AND" strength="20" xmlns:cts="http://marklogic.com/cts">
  <cts:word-query qtextpre="&quot;" qtextref="cts:text" qtextpost="&quot;">
    <cts:text>tile drainage</cts:text>
    <cts:option>punctuation-sensitive</cts:option>
    <cts:option>case-insensitive</cts:option>
    <cts:option>wildcarded</cts:option>
  </cts:word-query>
  <cts:or-query qtextjoin="OR" strength="10">
    <cts:word-query qtextref="cts:text">
      <cts:text>phosphorous</cts:text>
      <cts:option>punctuation-sensitive</cts:option>
      <cts:option>case-insensitive</cts:option>
      <cts:option>wildcarded</cts:option>
    </cts:word-query>
    <cts:word-query qtextref="cts:text">
      <cts:text>nitrogen</cts:text>
      <cts:option>punctuation-sensitive</cts:option>
      <cts:option>case-insensitive</cts:option>
      <cts:option>wildcarded</cts:option>
    </cts:word-query>
  </cts:or-query>
</cts:and-query>
'

Thank you,
Matthew
